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 invention discloses a video coding method, system and device, and the method comprises the steps: obtaining a current image set in a to-be-coded video according to a current frame and a coding sequence in the to-be-coded video; according to an inverse sequence opposite to the encoding sequence, sequentially performing reverse updating on the region of interest in each video frame in the current image set; and respectively calculating quantization parameters for the coding basic units in the updated region of interest and the updated non-region of interest in the current frame, so as to code each coding basic unit in the current frame according to the calculated quantization parameters. According to the technical scheme provided by the invention, the accuracy of video coding can be improved.

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...
