Abstract

The invention relates to the technical field of multimedia video image information processing, and discloses a video encoding method and system. The video encoding method includes: converting an input video stream into an RGB image; performing target detection and motion detection on the RGB image to identify RGB The target pixels and motion pixels of the image; the above-mentioned target pixels and motion pixels are fused to determine the pixels of interest and pixels of non-interest in the RGB image; according to the distribution of pixels of interest and pixels of non-interest, determine the region of interest and non-interesting regions; according to the set target code rate, the coding rate is allocated for the region of interest and the non-interesting region. The present invention makes the QP of the region of interest relatively small, and improves the definition of the region of interest.

Description

technical field [0001] The present invention relates to the technical field of multimedia video image information processing, in particular to a video coding method and system. Background technique [0002] At present, more and more conferences are moving from offline to online, and online conferences generally require high-definition image quality. The complexity of the network leads to the continuous change of network bandwidth, which brings more and more challenges to video compression and video transmission. , HD and UHD video compression coding is an essential technical means, and the performance and complexity of video compression coding also directly affect the application scope and potential of HD and UHD video. [0003] Therefore, under the condition of maintaining a certain video quality, improving the compression ratio of video coding and reducing the complexity of video coding are the commonly pursued goals. In the prior art, coding methods such as HEVC, H.264, ...
