The invention provides a video coding and decoding method and system based on a perceptual model, and relates to the technical field of video processing, and the method specifically comprises the steps: collecting a live broadcast image through a camera, and transmitting an original video frame stream to a collection server; the acquisition server updates the coding target parameters according to a subjective evaluation result fed back by the terminal equipment; performing compression coding on the original video frame stream based on the confrontation network structured coding model and the updated coding target parameter, and sending the compressed and coded data to a control center; the control center restores and decodes the compressed and coded data based on an adversarial network structured decoding model, and sends a video frame stream obtained by restores and decoding to the terminal equipment; the terminal equipment plays the video stream, collects a subjective evaluation result of a watching user, and uploads the subjective evaluation result to the control center; and the control center performs rationality verification on the subjective evaluation result based on the perception model. The coding complexity can be obviously reduced, and the user experience is improved.
Description
technical field [0001] The present application relates to the technical field of video processing, and in particular, to a method and system for video encoding and decoding based on a perceptual model. Background technique [0002] In recent years, with the development of intelligent terminals and the popularization of new services such as online video, the amount of video data transmitted in the network has exploded. The rapid development of ultra-high-definition video and panoramic video has further intensified the contradiction between supply and demand of bandwidth. With the change of emerging communication technologies such as 5G and the growing trend of 4K and 8K video demand, immersive communication has become an important development direction of future wireless multimedia communication, which can provide an immersive user experience for future 5G networks. Brand new multimedia service. In recent years, new immersive communication services represented by panoramic ...
