Abstract

The invention discloses an HEVC optimization algorithm based on visual saliency, and the algorithm comprises the following steps: firstly, establishing a high-definition lossless eye-tracking data setfor promoting the research of perceiving high-definition video compression; in a video saliency part, extracting static features of video frames through a VGG-16 network with enhanced spatial attention and the excellent performances of deep learning in image processing, and then processing long-range time domain information of a video through ConvLSTM to perform high-precision video saliency detection; in a high-definition video compression part, obtaining the saliency of the CU by using the predicted saliency map, so more subjective visual perception redundancy can be removed by using rate distortion optimization of perception saliency, the video compression effect is improved, the video compression time is shortened, and the video compression effect is further improved by using a QP selection algorithm of perception saliency.

Description

technical field [0001] The present invention relates to the technical field of video processing, and more specifically relates to a HEVC optimization algorithm based on visual saliency. Background technique [0002] With the emergence of ultra-high-definition television, digital television, smart phones, and webcasting, more and more high-definition and ultra-high-definition videos are transmitted and stored on streaming media, and the data volume of these high-definition videos is huge. Therefore, it is necessary to develop video compression standards to reduce video capacity. Based on these requirements, High Efficiency Video Coding is produced as an advanced video coding standard. [0003] High Efficiency Video Coding (HEVC) offers significant improvements in compression performance over existing standards. It achieves efficient video compression by reducing statistical redundancy and a small amount of perceptual redundancy in video. In terms of statistical redundancy, ...
