Description

[0002] With the development of computer technology, image processing technology is applied more and more. For example, in the scene of uploading video data to a cloud server by a terminal, after collecting the video, the terminal can perform image processing on each frame of image in the video, and upload the image data after processing to the cloud server.

[0003] In computer graphics, an RGB color model is composed of three color channels of red, green and blue, each channel occupies 8-bit color depth, a total of 24 bits, which contains all color information. In order to realize the transparency effect of graphics, another 8-bit additional information is added in the processing and storage of graphics files. This additional channel information representing the transparency of each pixel in the graphics is the Alpha channel. When the terminal uploads image data to the cloud server, since the original image data is RGB color data, after adding the Alpha channel, the image data uploaded by the terminal to the cloud server also includes additional information, which greatly increases the image data amount of a frame of image, resulting in that the terminal needs to occupy a large network resource when uploading image data to the cloud server.

Specifically, the display unit 230 can include a display screen 232 arranged on the front of the terminal 200. The display screen 232 can be configured in the form of a liquid crystal display, a light-emitting diode, or the like. The display unit 230 can be used to display various graphical user interfaces described in the present application.

[0077] The touch screen 231 can be overlaid on the display screen 232, or the touch screen 231 can be integrated with the display screen 232 to realize the input and output functions of the mobile terminal 200. After integration, the touch screen 231 can be referred to as a touch display screen. The display unit 230 in the present application can display application programs and corresponding operation steps.

[0078] The camera 240 can be used to capture still images or videos. An object projects an optical image through a lens to a photosensitive element. The photosensitive element can be a charge coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The photosensitive element converts the optical signal into an electrical signal, which is then passed to the processor 180 to be converted into a digital image signal.

[0079] The terminal 200 can also include at least one sensor 250, such as an acceleration sensor 251, a distance sensor 252, a fingerprint sensor 253, a temperature sensor 254. The terminal 200 can also be configured with a gyroscope, a barometer, a hygrometer, a thermometer, an infrared sensor, a light sensor, a motion sensor, and other sensors.

On the other hand, the microphone 262 converts the collected sound signal into an electrical signal, which is received by the audio circuit 260 and converted into audio data, which is then output to the RF circuit 210 for transmission to another terminal, for example, or to the memory 220 for further processing. In this application, the microphone 262 can obtain the user's voice.

[0081] Wi-Fi belongs to a short-range wireless transmission technology. The terminal 200 can help the user to send and receive emails, browse web pages, and access streaming media through the Wi-Fi module 270, which provides the user with wireless broadband Internet access.

[0082] The processor 280 is the control center of the terminal 200, which connects all parts of the terminal through various interfaces and lines, and performs various functions and processes data of the terminal 200 by running or executing software programs stored in the memory 220 and calling data stored in the memory 220. In some embodiments, the processor 280 can include one or more processing units; the processor 280 can also integrate an application processor and a baseband processor, wherein the application processor mainly processes the operating system, user interface, and application programs, and the baseband processor mainly processes wireless communication. It can be understood that the above-mentioned baseband processor can also not be integrated into the processor 280. In this application, the processor 280 can run the operating system, the application program, the user interface display and the touch response, and the processing method described in the embodiments of the application. In addition, the processor 280 is coupled with the display unit 230.

[0083] Bluetooth module 281 is configured to interact with other Bluetooth devices having Bluetooth modules via Bluetooth protocol.

[0084] Terminal 200 also includes a power supply 290 (e.g., a battery) to supply power to the various components. The power supply can be logically connected to processor 280 via a power management system, which can enable functions such as managing charging, discharging, and power consumption. Terminal 200 can also be configured with a power button to turn the terminal on and off, and to lock the screen, etc.

[0085] Figure 3 is a software structure block diagram of terminal 200 according to an embodiment of the present application.

[0086] The layered architecture divides software into several layers, each of which has a clear role and division of labor. Layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into four layers, from top to bottom, the application layer, the application framework layer, the Android runtime and system library, and the kernel layer.

[0087] The application layer can include a series of application packages.

[0088] As shown in Figure 3 , the application packages can include camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, video, short message, etc.

[0089] The application framework layer provides application programming interfaces (APIs) and programming frameworks for the applications of the application layer. The application framework layer includes some pre-defined functions.

[0090] As shown in Figure 3 , the application framework layer can include window manager, content provider, view system, phone manager, resource manager, notification manager, etc.

[0091] The window manager is used to manage window programs. The window manager can obtain the size of the display screen, determine whether there is a status bar, lock the screen, and take screenshots, etc.

[0092] The content provider is used to store and obtain data, and to make the data accessible to applications. The data can include videos, images, audio, dialed and received calls, browsing history and bookmarks, phonebook, etc.

[0093] The view system includes visual controls, such as controls that display text, controls that display pictures, etc. The view system can be used to build an application. A display interface can be composed of one or more views. For example, a display interface that includes a short message notification icon can include a view that displays text and a view that displays a picture.

[0094] The telephony manager is used to provide the communication function of the terminal 200. For example, the management of the call state (including the connection, hang-up, etc.).

[0095] The resource manager provides various resources for the application, such as localized strings, icons, pictures, layout files, video files, etc.

[0096] The notification manager enables the application to display notification information in the status bar, which can be used to convey a message of the notification type, which can automatically disappear after a short stay without user interaction. For example, the notification manager is used to notify the completion of the download, the message reminder, etc. The notification manager can also be a notification that appears in the top status bar of the system in the form of a chart or a scrolling text, such as a notification of an application running in the background, and can also be a notification that appears on the screen in the form of a dialog window. For example, the text information is prompted in the status bar, the prompt sound is emitted, the terminal is vibrated, the indicator light is blinked, etc.

[0097] The Android runtime includes the core library and the virtual machine. The Android runtime is responsible for the scheduling and management of the Android system.

[0098] The core library contains two parts: one part is the function function that the java language needs to call, and the other part is the core library of Android.

[0099] The application layer and the application framework layer run in the virtual machine. The virtual machine executes the java file of the application layer and the application framework layer into a binary file. The virtual machine is used to perform the management of the object life cycle, the stack management, the thread management, the security and exception management, and the garbage collection, etc.

[0100] The system library can include multiple functional modules. For example: the surface manager, the media library, the three-dimensional graphics processing library (for example: OpenGL ES), the 2D graphics engine (for example: SGL), etc.

[0101] The surface manager is used to manage the display subsystem and provides the fusion of 2D and 3D layers for multiple applications.

[0102] The media library supports multiple commonly used audio, video format playback and recording, and static image files, etc. The media library can support multiple audio and video coding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

[0103] The three-dimensional graphics processing library is used to realize three-dimensional graphics drawing, image rendering, synthesis, and layer processing, etc.

[0104] The 2D graphics engine is a drawing engine for 2D drawing.

[0105] The kernel layer is a layer between hardware and software. The kernel layer at least contains display drivers, camera drivers, audio drivers, and sensor drivers.

[0106] The following describes the working flow of the terminal 200 software and hardware in the capturing and photographing scenario.

[0107] When the touch screen 231 receives a touch operation, a corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the touch operation into a raw input event (including touch coordinates, a timestamp of the touch operation, and other information). The raw input event is stored in the kernel layer. The application framework layer obtains the raw input event from the kernel layer, and identifies the control corresponding to the input event. Taking the touch operation as a touch single-click operation, and the control corresponding to the single-click operation as the control of the camera application icon as an example, the camera application calls the interface of the application framework layer, starts the camera application, and then starts the camera driver through the kernel layer, and captures a still image or a video through the camera 240.

[0108] The terminal 200 in the embodiments of the present application can be a mobile phone, a tablet computer, a wearable device, a notebook computer, a television, or the like.

[0109] Figure 4 is a schematic diagram for showing a user interface on a terminal (for example, the terminal 200 of Figure 2 In some implementations, a user can open a corresponding application by touching an application icon on the user interface, or open a corresponding folder by touching a folder icon on the user interface.

[0110] It should be noted that the target object in the embodiments of the present application is a focus object in an image that a user pays attention to, for example, the target object can be a person, an animal, a building, a plant, or the like.

[0111] The following description takes a person as an example of the target object, and the image data transmission manner when the target object is another object is the same as that when the target object is a person.

[0112] The sending terminal collects a video containing a person through a camera, and decodes the video data collected by the camera to obtain an RGB image frame.

[0113] For any one frame of image, human body detection is performed on the person in the image to determine whether the image contains a person; if the image does not contain a person, the image is discarded, and the next frame of image is obtained by continuing to collect through the camera; after it is determined that the image contains a person, it is further determined whether the person is located outside the target region in the image.

[0114] The target region is a part of the image predetermined by the sending terminal and the receiving terminal, and since the color image data of the target region needs to be cropped when uploaded to the server, it is necessary to ensure that the person is not located in the target region.

[0115] For example, the target region can be the region at both ends of the image, and it is necessary to determine whether the person is located in the middle of the image; or the target region can be the region at the left end of the image, and it is necessary to determine whether the person is located in the right region of the image.

[0116] If it is determined that the person is not located outside the target region in the image, the sending terminal adjusts the focus of the camera, adjusts the shooting angle of the camera, and collects the next frame of image until it is determined that the person is located outside the target region in the image, and it is determined that the video image meeting the requirements is collected.

[0117] After the image containing the target object is collected through the camera, the sending terminal identifies the region where the target object is located in the image based on the trained image segmentation model; determines the transparency information corresponding to each pixel point in the image according to the region where the target object is located in the image and the background region other than the region where the target object is located; and generates additional image data of the image according to the transparency information corresponding to each pixel point in the image.

[0118] Each pixel point in the image of the embodiment of the present application corresponds to color image data and additional image data;

[0119] It should be noted that the additional image data of the embodiment of the present application can be additional image data of an alpha channel;

[0120] Alpha channel (α Channel or Alpha Channel) refers to the transparency and translucency of a picture. For example, a bitmap using 32 bits to store each pixel, every 8 bits respectively represents the color parameters of R channel, the color parameters of G channel, the color parameters of B channel, and the additional image data of alpha channel. In this case, the additional image data of alpha channel is a value in the range of 0-1, and the additional image data of alpha channel can represent 256 levels of translucency, because the alpha channel has 8 bits and can have 256 different data representation possibilities.

[0121] For example, after identifying the person region and the background region of the image based on the image segmentation model, the value of the additional image data of the alpha channel of the pixel point of the person region tends to 0, and the value of the additional image data of the alpha channel of the pixel point of the background region tends to 1.

[0122] The color image data of the embodiment of the present application comprises color parameters of multiple color channels;

[0123] For example, the color channels of the embodiment of the present application comprise R channel, G channel and B channel, and the color image data comprises color parameters of R channel, color parameters of G channel and color parameters of B channel.

[0124] After generating the additional image data of the image, the additional image data is divided into multiple additional image sub-data according to the number of color channels;

[0125] For example, the resolution of the image is 1920*1080, and the additional image data is divided into six additional image sub-data, and the pixel number corresponding to each additional image sub-data is 320*1080.

[0126] The sending terminal of the embodiment of the present application replaces the color image data of the target region of the image with the additional image data;

[0127] An optional implementation is that the sending terminal divides the additional image data into multiple equal additional image sub-data according to the number of color channels; and the sending terminal deletes the color parameters corresponding to the target region in the color parameters of each color channel; wherein the data amount of the color parameters corresponding to the target region in the color parameters of each color channel is not less than the data amount of the additional image sub-data; and the sending terminal adds the multiple equal additional image sub-data to the positions corresponding to the target region in the color parameters of each color channel according to a preset replacement rule.

[0128] It should be noted that, since the sending terminal of the embodiment of the present application replaces the color image data of the target region of the image with the additional image data, and the color image data of the target region of the image is composed of the color parameters of each color channel, and the multiple equal additional image sub-data after division needs to be added to the color parameters of each color channel uniformly, the additional image data needs to be divided uniformly according to the number of color channels;

[0129] For example, the embodiment of the present application comprises three color channels, and the additional image data needs to be divided into N additional image sub-data, and N is a multiple of 3.

[0130] When the sending terminal of the embodiment of the present application replaces the color image data, the color image data of the target region needs to be deleted first, and then the additional image data after division is added to the position of the color image data of the target region after deletion.

[0131] As shown in the resolution of the RGB image of 1920*1080, the image is segmented by using a person segmentation algorithm to obtain an alpha channel image as shown in Figure 5 Figure 6 Figure 6 The values of all pixel points in the alpha channel image shown in the image form the additional image data of the image;

[0132] The additional image data of the image is evenly divided into six parts, that is, the alpha channel image shown in Figure 6 is divided into 6 regions, that is, the size of each region is 320*1080.

[0133] The sending terminal clips the color parameters of each color channel of the collected image, and clips the color parameters corresponding to the target region in each color channel;

[0134] For example, the target region is the region at the left and right ends of the image; as shown in the resolution of the RGB image of 1920*1080, the dashed box marked is the target region set in advance in the image, and the size of the target region is 320*1080. The target region of the image is clipped; since each channel of the RGB image is taken out alone It is a gray image with the same size as the original image, and each channel gray image is represented by R, G, and B, so the target region of each channel gray image is clipped, and the clipped R, G, and B are shown in Figure 5 Figure 7

[0135] When the sending terminal replaces the color image data of the target region of the image with the additional image data, the replacement is performed according to the preset replacement rule;

[0136] For example, referring to the additional image data division mode shown in Figure 6 and the R, G, and B images after clipping shown in Figure 7 The replacement rule of the present application embodiment can be:

[0137] According to the order of the alpha channel image from left to right, the additional image sub-data of each region after division is marked as 1, 2, 3, 4, 5, and 6, respectively;

[0138] The additional image sub-data of region 1 is added to the target region clipped at the left end of the R image;

[0139] The additional image sub-data of region 2 is added to the target region clipped at the right end of the R image;

[0140] The additional image sub-data of region 3 is added to the target region clipped at the left end of the G image; ​​​​

[0141] adding the additional image sub-data of region 4 to the target region cropped off at the right end of the G image;

[0142] adding the additional image sub-data of region 5 to the target region cropped off at the left end of the B image;

[0143] adding the additional image sub-data of region 6 to the target region cropped off at the right end of the B image.

[0144] The color image data of the target region of the image is replaced by the additional image data as described above, and after the replacement is completed, image data with the same size as the color image data of the original image is obtained, which includes the additional image data of the image and the color image data of other regions except the target region; the sending terminal uploads the image data obtained after the replacement to the server.

[0145] The receiving terminal of the embodiment of the present application can obtain image data from the server, determine additional image data for representing transparency information of each pixel point in the image from the obtained image data, and obtain color image data of other regions except the target region in the image data; and generate a target image according to the obtained color image data of other regions and the additional image data.

[0146] Since the image data obtained by the receiving terminal from the server is uploaded by the sending terminal, and the image data uploaded by the sending terminal to the server replaces the color image data of the target region of the image by the additional image data as described above, the image data obtained by the receiving terminal from the server includes the additional image data and the color image data of other regions except the target region.

[0147] When the receiving terminal determines the additional image data from the obtained image data, the following methods can be specifically used:

[0148] The receiving terminal extracts additional image sub-data from the positions corresponding to the target region in the color parameters of each color channel according to a preset replacement rule; and the receiving terminal groups the extracted multiple additional image sub-data into additional image data.

[0149] It should be noted that the preset replacement rule is a replacement rule agreed upon by the sending terminal and the receiving terminal in advance, so that after the receiving terminal receives the image data, the image data can be accurately parsed and the additional image data of the image can be restored.

[0150] The image data received by the receiving terminal includes image data of an R channel, image data of a G channel, and image data of a B channel; and the image data of the R image, the G image, and the B image all contain additional image sub-data.

[0151] For example, as shown in the R image, the G image, the B image, and the left and right ends of each image are additional image sub-data added; Figure 8

[0152] In generating the additional image, the receiving terminal restores the additional image data according to a preset replacement rule:

[0153] The left end of the R image is cropped to a region with a size of 320x1080, numbered as region 1; similarly, the right side is also cropped to a region with a size of 320x1080, numbered as region 2;

[0154] The left end of the G image is cropped to a region with a size of 320x1080, numbered as region 3; similarly, the right side is also cropped to a region with a size of 320x1080, numbered as region 4;

[0155] The left end of the B image is cropped to a region with a size of 320x1080, numbered as region 5; similarly, the right side is also cropped to a region with a size of 320x1080, numbered as region 6;

[0156] Finally, the images in the alpha channel with a size of 1920x1080 are obtained by splicing in the order of the numbers, and the spliced image in the alpha channel is as shown in Figure 9

[0157] It should be noted that the pixel values of the image in the alpha channel obtained by splicing in the embodiments of the present application form the additional image data; after the images in each color channel are cropped, the data of each pixel point in the retained region is the color image data of other regions.

[0158] After the additional image data and the color image data of other regions are determined from the obtained image data, the present application generates a target image;

[0159] In the implementation, the receiving terminal determines the color parameters of other regions corresponding to each color channel from the color image data of other regions; for any one color channel, the receiving terminal determines the color parameters of all regions corresponding to the color channel according to the color parameters of other regions corresponding to the color channel and the preset color parameters of the target region corresponding to the color channel; the receiving terminal generates a reference image according to the color parameters of all regions corresponding to each color channel; and generates a target image according to the reference image and the additional image data.

[0160] ​​Since the image data obtained by the receiving terminal from the server only contains color image data of other regions, the receiving terminal needs to determine color image data of the target region when restoring the image; the embodiment of the application pre-sets preset color parameters of the target region corresponding to each color channel in the receiving terminal, so that the receiving terminal can generate a complete reference image according to the color image data of other regions obtained from the server and the preset color parameters of the target region corresponding to each color channel.

[0161] In implementation, the receiving terminal can first generate an image corresponding to each color channel, and then superimposes the images corresponding to each color channel to obtain a complete reference image.

[0162] In implementation, the receiving terminal can first generate an image corresponding to each color channel, and then superimposes the images corresponding to each color channel to obtain a complete reference image.

[0163] The reference image generated by the receiving terminal of the embodiment of the application can be an RGB image.

[0164] In addition, the receiving terminal of the embodiment of the application generates a target image according to the reference image and additional image data after generating the reference image.

[0165] In implementation, the receiving terminal generates an image of an alpha channel according to the parsed additional image data, superimposes the image of the alpha channel and the reference image to generate a target image.

[0166] For example, as shown in FIG. 4, the reference image A and the image B of the alpha channel are superimposed to obtain the target image C. Figure 10

[0167] After generating the target image, the receiving terminal of the embodiment of the application can process the target image based on the additional image data corresponding to the target image.

[0168] For example, since the additional image data is used to represent transparency information of each pixel point in the target image, the additional image data can be used to distinguish the person and the background in the target image, and the receiving terminal can flexibly replace the background region of the target image based on the additional image data.

[0169] It should be noted that the way in which the receiving terminal replaces the background region of the target image according to the additional image data is one of the processing manners in which the receiving terminal processes the target image according to the additional image data, and the way in which the receiving terminal processes the target image according to the additional image data is not limited to the above example.
