Problems solved by technology

But in fact, in the area of ​​interest to the human eye, not every position is the focus of the human eye, so the current encoding method is still not accurate enough

Embodiment Construction

[0013] In order to make the purpose, technical solution and advantages of the present application clearer, the following will clearly and completely describe the technical solution of the present application in combination with specific implementation methods of the present application and corresponding drawings. Apparently, the described implementations are only some of the implementations of this application, not all of them. Based on the implementation manners in this application, all other implementation manners obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0014] An embodiment of the present application provides a video coding method, which can perform coding on each video frame in the video to be coded. In practical applications, each video frame in the video to be encoded may have its own saliency image. The saliency image can be an image whose width (Width, W) and height (Heigh...

Abstract

The present invention discloses a video coding method, system and equipment, wherein the method includes: obtaining the current image set in the video to be coded according to the current frame and the coding sequence in the video to be coded; In the reverse order of the opposite order, reversely update the regions of interest in each video frame in the current image set in turn; calculate the coding basic units for the updated regions of interest and non-interest regions in the current frame respectively A quantization parameter is used to encode each coding basic unit in the current frame according to the calculated quantization parameter. The technical solution provided by this application can improve the accuracy of video coding.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a video encoding method, system and equipment. Background technique [0002] With the continuous development of high-definition video, the bandwidth required to transmit high-definition video is also increasing. Considering the cost of bandwidth, when encoding high-definition video, different bit rates are usually assigned to different areas in the video frame, so that the key areas can be as clear as possible while keeping the total bit rate unchanged. degree increase. [0003] In order to realize the above-mentioned solution, when encoding the video, it is necessary to identify the areas of interest to the human eye in each video frame, and then allocate more code rates to the areas of interest to the human eye, while for other parts of the area Less code rate can be allocated. In this encoding method, the same quantization parameter is usually used for enco...
