AI Technical Summary

Problems solved by technology

However, only to improve the encoding method, there is little room for improvement
In fact, the information contained in the video image has a large part of redundancy compared to the image information that the human eye can perceive, and the commonly used video compression algorithms ignore the visual effects of the human eye to compress video data.

Abstract

The invention provides a video compression method and a video compression device. The video compression method comprises steps that to-be-compressed video data is acquired; every frame of image of the video data is extracted; a tensor model is established for every frame of image; the vision perturbation processing of the tensor model of every frame of image is carried out; the low-rank approximation processing of the tensor model of every frame of image is carried out, and then the compressed video data is acquired. The above mentioned video compression method is combined with human eye vision characteristics, the video compression is realized effectively.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a video compression method and device. Background technique [0002] Video compression technology is the premise of computer processing video data. The purpose of video compression is to reduce the space of video storage or reduce the bandwidth of video transmission. Even today when storage and bandwidth are relatively cheap, in the face of people's strong demand for high-definition video, it is almost impossible to achieve large-capacity storage and real-time transmission of video without video compression. [0003] Commonly used video compression algorithms basically split the video data into images first, and then use the image coding method to encode the images to realize the compression of the images, and then realize the compression of the video data. Improving the coding algorithm is the main way to improve the performance of the video compression algorit...
