Skipping coding mode pre-judgment method for highly efficient video coding standard

Abstract

The invention provides a skipping coding mode pre-judgment method for a highly efficient video coding standard. The objective of the invention is to solve problems of quite high complexity of current standard coding and quite long coding time. The method comprises following steps of calculating the rate-distortion cost of a coding block so as to acquire a movement vector and residual information; using the size of the moving vector and the residual information to judge whether the coding block is a skipping mode, if no, entering the next top, or else, processing the next coding block; calculating rate-distortion cost of the previous frame of a coding block adjust the current coding block and the next frame of the coding block; using the size of the moving vector and the residual information to judge adjacent coding blocks and using a entropy difference concept to replace tediously calculated interactive information. According to the invention, a skipping mode is rapidly judged; when excellent coding performance is obtained, massive coding time is saved; the method has actual operability, so it is facilitated that real time application is performed; and when the video coding efficiency is not reduced, massive coding time is saved.

Description

technical field [0001] The present invention relates to the technical field of video coding, in particular to a skip coding mode early judgment method for high-efficiency video coding standards, a method for judging coding modes in video coding, and in particular to a high-efficiency video coding standard A fast detection skip mode method. Background technique [0002] In recent years, people's demand for video information, especially high-definition video and various network videos, has been increasing, and video compression technology has faced great challenges. The Motion Picture Experts Group (MPEG) of ISO / IEC and the Video Coding Expert Group (VCEG) of ITU-T formed the Joint Collaborative Team on Video Coding (JCT-VC), And jointly formulated the high-efficiency video coding standard H.265 / HEVC (High Efficiency Video Coding). The new generation of video coding standard H.265 / HEVC has added many new coding tools. Compared with the previous generation of video coding sta...
