Video coding method and system based on H265 and electronic equipment

Abstract

The invention provides an H265-based video coding method and system and electronic equipment, and the method comprises the steps: carrying out the image quality optimization and QP processing of an image of a video frame, enabling the optimized image and a QP matrix to serve as the input of an H265 encoder, setting the QP value of a corresponding position in an encoder output frame through the H265 encoder according to the specific QP value in the QP matrix, and carrying out the QP processing of the video frame. According to the scheme, image frame quality enhancement is carried out on the basis of a standard H265 encoder, intra-frame distribution is carried out on the output code rate according to a human eye attention mechanism, the compression rate higher than that of the standard H265 video encoder can be achieved, and compared with the prior art, the method has the advantages that the method is easy to implement, and the cost is low. According to the method, the video quality optimization model and the mask generation model can be integrated into a standard H265 coding framework, a deep learning model does not need to be deployed at a decoding end, and the method can be compatible with most of mobile terminal equipment.

Description

Technical field [0001] The present invention relates to the field of video compression, and more particularly to a video encoding method, system, and electronic device based on H265. Background technique [0002] With the popularity of each video platform, people have become more close and closer in working life, which has challenged video transmission and storage, and also prompts video compression technology to have further developed. At the same time, with the gradual maturity of artificial intelligence and large data technology, its application in security, entertainment, industrial, etc. is increasingly widely used, and video coding technology that combines deep learning is increasingly valued. [0003] At present, the mainstream method is the end-to-end video codec structure in terms of depth learning video codec, which uses a depth learning model with a depth learning model to perform video decoding in the video decoding end. The mainstream end-to-end video compression fra...
