Depth correlation-based inter-frame fast encoding method for coding screen content

Abstract

The present invention discloses a depth dependence-based inter-frame fast coding method for coding the screen content. The method mainly solves the technical problem that the computation complexity is high in the prior art. According to the technical scheme of the invention, on the condition that an optimal prediction mode at the current depth is a skip prediction mode, conducting the statistics on the probability of the above optimal prediction mode to be a candidate prediction mode at the next depth and coding the candidate prediction mode; during the coding process of the candidate prediction mode, conducting the statistics on the probability of an optimal motion mode and judging whether the probability of the optimal motion mode is equal to the probability of advanced motion vector prediction (AMVP) motion estimation or the probability of motion merge estimation; selecting an optimal motion estimation method that is largest in the probability of candidate prediction mode and coding the optimal motion estimation method; recording the optimal prediction mode at the current depth and selecting a candidate prediction mode for the next depth inter-frame prediction. In this way, the number of candidate prediction modes at the next depth is reduced. According to the technical scheme of the invention, on the premise that the video coding efficiency is not influenced at all, the coding time is shortened. The method can be used for video processing.

Description

technical field [0001] The invention belongs to the technical field of video processing, in particular to an inter-frame fast coding method in screen content coding SCC, which is used for the inter-frame coding process of screen content video in non-continuous tone areas. Background technique [0002] With the continuous improvement of people's quality of life and demand, driven by people's life, entertainment and office, video communication technology not only requires higher and higher definition, but also shows diversification in content. In January 2013, High Efficiency Video Coding (HEVC) has made a great leap in processing natural video codecs and has become the latest international video coding standard. Traditional video encoders have high coding efficiency for natural video in continuous tone areas, but the encoding effect for screen content video in non-continuous tone areas generated by computers is not ideal. Therefore, based on HEVC, a non-camera capture method ...

Problems solved by technology

However, when the CFM method is combined with the ESD method to encode the screen content, the encoding time is hardly reduced, and the encoding efficiency is reduced, which does not play a role in fast encoding.

Therefore, on the basis of using the ESD method, the encoding time of SCC needs to be reduced
