[0031] See also Figure 1 , is a schematic diagram of an exemplary system architecture for applying an embodiment of the present disclosure.

[0032] like Figure 1 As shown, the system architecture 100 may include a terminal device 102, a network 103 and a server 104. It should be understood that Figure 1 The number or type of terminal devices, networks, and servers in the embodiment are merely illustrative. Any number or type of terminal devices, networks, and servers may be provided as required.

[0033] The network 103 is used to provide a medium for communication links between terminal devices and servers. The network 103 may include various connection types, such as wired or wireless communication links or optical fiber cables.

[0034] The terminal device 102 can interact with the server through the network 103 to receive or send requests or information, etc. The terminal device 102 can be various electronic devices, including but not limited to smart phones, tablet computers, smart wearable devices, personal digital assistants, etc.

[0035] The server 104 can store, analyze, and process the received data, and can also send control commands or requests to terminal devices or other servers. The server can provide services in response to user service requests. It is understood that a server can provide one or more services, and the same service can also be provided by multiple servers.

[0036] based on Figure 1 In the system architecture shown, in the embodiment of the present disclosure, the user 101 can input the first image and preset parameters through the terminal device 102, and the terminal device 102 sends the first image and preset parameters to the server 104 through the network 103. After receiving the first image and the preset parameters, the server 104 can perform stylized camera movement processing based on the first image and the preset parameters to obtain multiple frames of second images, and then generate a target video based on the multiple frames of second images. Finally, the server 104 can return the target video to the terminal device 102 through the network 103, so that the user 101 can watch the effect of the target video through the terminal device 102.

[0037] See also Figure 2 , is a schematic diagram of a link scenario for generating a video according to an exemplary embodiment.

[0038] like Figure 2 As shown, first, the user can input image A and preset parameters through a third-party application installed on the terminal device. Then, the terminal device can send a request Q to the cloud editing platform of the video, wherein the request Q carries image A and preset parameters to upload image A and preset parameters to the cloud editing platform of the video. The cloud editing platform of the video can transmit image A and preset parameters to the algorithm server under the instruction of request Q. The algorithm server can generate multi-frame video frame images frame by frame based on image A and preset parameters through mirror processing and stylization processing, and generate video C based on the generated multi-frame video frame images, and return video C to the cloud editing platform. The cloud editing platform can then reprocess video C based on a preset video template (for example, adding special effects, etc.) to obtain video D. Finally, the cloud editing platform can return video D to the terminal device, and the terminal device plays video D for the user to watch.

[0039] See also Figure 3 , is a schematic diagram of a scene for generating a video according to an exemplary embodiment.

[0040] like Figure 3 As shown, first, obtain the reference image T and the preset parameters, and determine the total number of frames of the target video as n by parsing the preset parameters. Take the reference image T as the first frame to be processed, and perform a loop operation to generate multiple video frame images. In the first loop operation, the reference image T is first stylized to obtain the stylized image T1. Then, the stylized image T1 is processed by moving the camera to obtain the moving camera image T2. Then, the moving camera image T2 is processed by moving the camera to obtain the moving camera image T3, and the stylized image T1 and the moving camera image T2 are used as video frames. Next, it is determined that the generated video frame is 2, which is less than the total number of frames of the target video n, so the second loop operation is entered... Until in the mth loop operation, after obtaining the generated video frame, it is determined that the generated video frame is greater than or equal to the total number of frames of the target video n, then the loop operation can be stopped. And based on the generated video frame, the target video is generated.

[0041] The present disclosure will be described in detail below in conjunction with specific embodiments.

[0042] Figure 4 The flowchart of a method for generating a video according to an exemplary embodiment is shown. The execution subject of the method can be implemented as any device, platform, server or device cluster with computing and processing capabilities. The method includes the following steps:

[0043] like Figure 4 As shown, in step 401, a first image and preset parameters are obtained.

[0044] In this embodiment, the first image is a first frame reference image used to generate a target video. In one implementation, a frame of image directly input by a user can be used as the first image. In another implementation, a frame of image directly shot by a user can be used as the first image. In yet another implementation, a frame of image selected by a user from an existing video can be used as the first image. It can be understood that this embodiment does not limit the specific method for obtaining the first image.

[0045] In this embodiment, the preset parameters may be system defaults or user settings. The preset parameters may include, but are not limited to, camera movement parameters for camera movement processing, stylized parameters for stylized processing, and image parameters for determining the duration and size of the target video. Among them, the camera movement parameters may include, but are not limited to, image translation coefficients, rotation coefficients, scaling coefficients, lens zoom coefficients, etc. The user can control the camera movement effect of the generated video by setting the camera movement parameters. The stylized parameters may include, but are not limited to, stylized guide words, the identifier of the selected stylized model, etc. The user can guide the stylized effect of the generated video by setting the stylized parameters. The image parameters may include, but are not limited to, the duration of the target video (used to determine the number of video frames included in the target video), the size of the target video, the image resolution of the target video, etc.

[0046] In step 402, stylized camera movement processing is performed based on the first image and preset parameters to obtain multiple frames of second images.

[0047] In this embodiment, the first image can be used as the first frame of the image to be processed, and the camera movement processing and stylization processing can be performed alternately according to preset parameters to generate multiple frames of the second image frame by frame. For example, image a1 is the first image, and image a1 can be processed to generate image a2, and then image a2 can be processed to generate image a3, and then image a3 can be processed to generate image a4, and then image a4 can be processed to generate image a5... and so on, and finally, part or all of the generated images are used as the second image.

[0048] Specifically, first, the number of video frames of the target video and the image size and resolution of the target video can be determined according to the image parameters included in the preset parameters. Then, the first image is used as the first frame to be processed, and stylization processing and camera movement processing are alternately performed according to the stylization parameters and camera movement parameters included in the preset parameters, and multiple frames of second images are generated frame by frame according to the number of video frames of the target video and the image size and resolution of the target video.

[0049] In this embodiment, the target operation can be performed multiple times to alternately perform stylization processing and camera movement processing. Among them, one target operation can include: first, obtaining the current image to be processed, when the target operation is performed for the first time, the current image to be processed is the first image, and when the target operation is not performed for the first time, the current image to be processed is obtained based on the image generated in the last target operation. Then, according to preset parameters, the current image to be processed can be stylized to obtain a stylized image, and based on the stylized image, at least one camera movement processing can be performed to obtain at least one frame of camera movement image, and the stylized image and at least part of the camera movement image are used as the second image.

[0050] In one implementation, the stylized image may be subjected to a camera movement process to obtain a frame of camera movement image. The frame of camera movement image is used as the image to be processed for the next target operation. For example, in the nth target operation, image b1 is the current image to be processed, and image b1 may be first subjected to a stylized process to generate a stylized image b2, and then subjected to a camera movement process to generate a camera movement image b3, and the stylized image b2 and the camera movement image b3 are used as the second image. In the n+1th target operation, the camera movement image b3 may be used as the current image to be processed, and the camera movement image b3 may be subjected to a stylized process.

[0051] In another implementation, the stylized image may be subjected to multiple camera movement processing to obtain multiple frames of camera movement images, and the stylized image and one of the multiple frames of camera movement images are obtained as the second image. For example, in the nth target operation, image c1 is the current image to be processed, and image c1 may be first subjected to stylized processing to generate stylized image c2, and then subjected to camera movement processing to generate camera movement image c3, and then subjected to camera movement processing to generate camera movement image c4, and the stylized image c2 and the camera movement image c3 are used as the second image. In the n+1th target operation, the camera movement image c4 may be used as the current image to be processed, and the camera movement image c4 may be subjected to stylized processing.

[0052] In another implementation, the stylized image may be subjected to multiple camera movement processing to obtain multiple frames of camera movement images, and the stylized image and all the multiple frames of camera movement images are obtained as the second image. For example, in the nth target operation, image d1 is the current image to be processed, and image d1 may be first subjected to stylized processing to generate stylized image d2, and then stylized image d2 is subjected to camera movement processing to generate camera movement image d3, and then camera movement image d3 is subjected to camera movement processing to generate camera movement image d4, and then camera movement image d4 is subjected to camera movement processing to generate camera movement image d5, and camera movement image d3, camera movement image d4, camera movement image d5 and stylized image d2 are used as the second image. In the n+1th target operation, camera movement image d5 may be used as the current image to be processed, and camera movement image d5 may be subjected to stylized processing.

[0053] It should be noted that the camera movement processing may be any reasonable camera movement algorithm. Any camera movement algorithm known in the art or that may appear in the future may be applied to the present disclosure. The present disclosure does not limit the specific method of the camera movement algorithm.

[0054] In addition, the image may be stylized based on the stylized parameters included in the preset parameters. For example, the stylized parameters may include the corresponding relationship between the number of video frames and the stylized model. For example, the nmth frame image may be stylized using the model M1, the stth frame image may be stylized using the model M2, and so on.

[0055] In step 403, a target video is generated based on the multiple frames of second images.

[0056] In this embodiment, after generating multiple frames of second images, a target video can be generated based on the multiple frames of second images. In one implementation, if the first image is a frame of image uploaded separately, the first image can be used as the first frame of image, and the multiple frames of second images can be synthesized into the target video.

[0057] In another implementation, if the first image is a frame of image selected from an existing video, the existing video and multiple frames of second images may be combined to form a target video.

[0058] In another implementation, after the first image and multiple frames of the second image are synthesized into a video, special effects may be added to the synthesized video to obtain a target video.

[0059] It is understandable that the target video may be synthesized in any other reasonable manner, and this embodiment does not limit the specific manner of synthesizing the target video.

[0060] The present disclosure provides a method for generating a video, which obtains a first image and preset parameters, performs stylized camera movement processing based on the first image and the preset parameters, obtains multiple frames of second images, and generates a target video based on the multiple frames of second images. Thus, it is possible to efficiently generate a stylized video containing spatial camera movement based on a frame of existing image, which not only improves the generation efficiency of the target video, but also improves the video effect and user experience.

[0061] Figure 5 FIG. 1 is a flowchart of another method for generating a video according to an exemplary embodiment. The embodiment describes a process of generating a target video, including the following steps:

[0062] like Figure 5 As shown, in step 501, a first video is obtained, and preset parameters are obtained, and in step 502, a frame of image is obtained from the first video as a first image.

[0063] In this embodiment, a user may upload a video as the first video, and any frame of image may be obtained from the first video as the first image. In one implementation, a user may select any frame of image from the video as the first image. In another implementation, a frame of image that meets the conditions may be selected as the first image based on a preset rule. For example, the image that meets the conditions may be an image with specified features, etc. It is understood that the first image may also be obtained from the first video in any other reasonable manner, and this embodiment does not limit this aspect.

[0064] In step 503, stylized camera movement processing is performed based on the first image and preset parameters to obtain multiple frames of second images.

[0065] In step 504, a target video segment in the first video is obtained, and in step 505, the target video segment is spliced ​​with multiple frames of second images to obtain a target video.

[0066] In this embodiment, a target video segment can be obtained from the first video, and the target video segment can include the first image and at least part of the video frame image before the first image. Then, multiple frames of the second image are sequentially spliced ​​with the target video segment to obtain the target video.

[0067] It should be noted that Figure 4 The same steps as in the embodiment, in the above Figure 5 The embodiments will not be described in detail. For related contents, please refer to Figure 4 Example.

[0068] This embodiment obtains a first image from an existing video, performs stylized camera movement processing based on the first image and preset parameters to obtain multiple frames of second images, obtains a target video segment from the existing video, and splices the target video segment with the multiple frames of second images to obtain the target video. Thus, a stylized video with spatial camera movement can be generated based on a frame of an existing video, further improving the video effect and user experience.

[0069] It should be noted that although the operations of the method of the disclosed embodiment are described in a specific order in the above embodiments, this does not require or imply that the operations must be performed in this specific order, or that all the operations shown must be performed to achieve the desired results. On the contrary, the steps depicted in the flowchart can change the order of execution. Additionally or alternatively, some steps can be omitted, multiple steps can be combined into one step for execution, and / or one step can be decomposed into multiple steps for execution.

[0075] In some implementations, the processing module 602 may include: a processing submodule (not shown in the figure).

[0076] The processing submodule is used to take the first image as the first frame to be processed according to the preset parameters, perform stylization processing and camera movement processing alternately, and generate multiple frames of second images frame by frame.

[0077] In other embodiments, the processing submodule may generate multiple frames of the second image frame by frame by performing the following target operation multiple times: obtaining the current image to be processed, wherein when the target operation is performed for the first time, the current image to be processed is the first image, and when the target operation is not performed for the first time, the current image to be processed is obtained based on the image generated in the last target operation. According to preset parameters, the current image to be processed is stylized to obtain a stylized image, and based on the stylized image, at least one camera movement process is performed to obtain at least one camera movement image. The stylized image and at least part of the camera movement image are obtained as the second image.
