Embodiment 1

[0050] An embodiment of the present disclosure provides a data encoding method, such as figure 1 As shown, the data encoding method includes the following steps:

[0051] 101. Acquire the target image frame sequence, which is generated according to the display screen within the preset time period of the terminal device

[0052] Before the acquisition of the target image frame, acquisition of the display screen of the terminal device is also included, and the acquisition method may include acquisition through software or hardware. For example, the display screen of the terminal device is obtained through screen recording software or through an image collector.

[0053] The aforementioned terminal equipment may be terminal equipment such as computers and mobile phones.

[0054] In a specific implementation, the target image frame sequence may be generated after acquiring ten seconds of display images of the computer desktop.

[0055] 102. Acquire a change frequency correspond...

example 1

[0058] Example 1: Obtain the change frequency corresponding to the target image frame sequence through the command of the terminal device to the display screen:

[0059] Obtaining instruction information generated by the terminal device for the display screen;

[0060] Analyzing the instruction information, and determining whether the instruction information includes a word processing instruction according to the analysis result;

[0061] When the instruction information includes a word processing instruction, obtain the generation frequency of the word processing instruction;

[0062] According to the generation frequency of the word processing instruction, the change frequency corresponding to the target image frame sequence is acquired.

[0063] The above word processing instruction may be a word processing instruction such as Text Rendering Hint (text rendering instruction), DrawString (drawing string instruction).

[0064] The method provided in the present disclosure c...

example 2

[0065] Example 2: Obtain the change frequency corresponding to the target image frame sequence through the content of the target image frame sequence:

[0066] Comparing the current image frame in the image frame sequence with the next image frame corresponding to the current image frame frame by frame, and obtaining the number of changes corresponding to the image frame sequence;

[0067] According to the number of changes, the change frequency corresponding to the target image frame sequence is acquired.

[0068] Here, taking the sequence of image frames in time order, including image frame A, image frame B, image frame C, image frame D, image frame E, and image frame F as an example, the acquisition of the number of changes is described. Whether the image frame is the same as the next image frame is compared frame by frame, and when the image frame is different from the next image frame, the number of changes is determined. After frame-by-frame comparison, image frame A is...

Abstract

The invention provides a data encoding method and device, and relates to the technical field of electronic information, capable of solving the problem of resource waste during encoding processing of image frames. The specific technical scheme includes the steps: generating a target image frame sequence after a display image of terminal equipment is acquired; calculating the change frequency corresponding to the target image frame sequence according to a preset algorithm; and according to the change frequency, when the change frequency is greater than a preset value, performing encoding processing on the target image frame sequence according to a first encoding rule, and when the change frequency is less than or equal to the preset value, performing encoding processing on the target image frame sequence according to a second encoding rule. The present disclosure is used for image encoding.

Description

technical field [0001] The present disclosure relates to the technical field of electronic information, in particular to a data encoding method and device. Background technique [0002] With the development of information technology, people's requirements for communication services are constantly increasing, and the contradiction between image communication and communication network capacity is becoming increasingly prominent. Especially for video image communication, due to its huge amount of data, it will be difficult to transmit and store data without image compression. Therefore, image compression capability is particularly important for video images. [0003] Image codecs in the prior art mainly implement image compression through inter-frame and intra-frame de-redundancy methods, but this redundancy is only for the image itself, and no coding process is performed for visual redundancy. Visual redundancy is relative to the visual characteristics of the human eye, and ...
