Benefits of technology

This patented method improves image compression by breaking down older methods into smaller parts that are more efficient at compressing high-quality images compared to current techniques like JPEG or MIFF (Moving Picture Experts Group).

Problems solved by technology

Technological Problem: Traditional videos have been compressed without any improvement from advanced methods like High Definition Content Protection (HDCP). Additionally, there were limitations related to how well they could handle certain types of data or provide better results during decompression due to their lacked structure. Overall, current technical problem addressed in this patents relates to improving video compression while maintaining good quality images captured under different conditions.

Abstract

The invention relates to a video coding and decoding system based on keyframe super-resolution reconstruction, belonging to the technical field of video image processing. The video coding and decoding system comprises a video coding end and a video decoding end, wherein the video coding end comprises a frame selection module, a keyframe coding module, a small wave downsampling module, a non-keyframe coding module and a code stream integrating module; and the video decoding end comprises a code stream decomposing module, a keyframe decoding module, a small-wave decomposing module, a non-keyframe decoding module, a non-keyframe upsampling module and a video integrating module. The invention is used for downsampling videos before coding and enhancing resolution of the videos by adopting a video super-resolution reconstruction technology based on keyframe layered block matching after decoding, thereby reducing the bit rate of video code streams after the coding and realizing the enhancement of coding efficiency.
