AI Technical Summary

Problems solved by technology

[0003] Existing image compression algorithms mainly include fractal compression coding algorithms, but in the process of fractal image coding, it is necessary to search for the best matching block in a massive codebook, which takes a lot of time and is not conducive to the promotion and application of fractal image compression coding. And there will be "block effect" in the encoding process, which also affects the reconstructed image quality

Abstract

The invention relates to the technical field of image compression, and discloses a video stream detection-based image compression method, which comprises the following steps of: obtaining a video stream to be detected, detecting a target image in the video stream by using a target detection model, and extracting the target image; pruning convolution kernels and parameters in the target detection model by using an adaptive pruning algorithm, and extracting target image features by using the pruned target detection model; segmenting the features of the target image by using a feature segmentation method based on a sliding window; and performing encoding processing on the segmented features by using a transform domain-based encoding sampling algorithm to complete compression of the target image. The invention further provides an image compression system based on video stream detection. According to the invention, image compression is realized.

Description

technical field [0001] The invention relates to the technical field of image compression, in particular to an image compression method and system based on video stream detection. Background technique [0002] With the rapid iterative update of mobile devices, people can search for the information they need in time and transfer it to each other. Simple text transmission of information can no longer meet the demand. As the carrier of information transmission, language and images are more and more popular, and the frequency of use is gradually increasing. Images, in particular, convey information that words and language cannot replace. At the same time, with the development of informatization, the amount of video in the network is also increasing. How to obtain the desired image from the video stream and efficiently transmit image data information will become a hot topic of current research. [0003] Existing image compression algorithms mainly include fractal compression cod...
