Weighted universal image compression [PDF]
We describe a general coding strategy leading to a family of universal image compression systems designed to give good performance in applications where the statistics of the source to be compressed are not available at design time or vary over time or ...

Lossy Image Compression Using PCA and Contourlet Transform
With the rapid development of Internet, image information is growing. It requires a lot of image storage and transmission. In order to reduce the storage and get better image quality, image compression algorithm is studied. The paper proposes a new image

A novel image compression technology based on vector quantisation and linear regression prediction
In the information age, a digital image is an important media for people’s daily interactions. Looking to maintain the quality of the restored image, how to maximise the compression of images has become a challenging topic.

An End-to-End Deep Learning Image Compression Framework Based on Semantic Analysis
Lossy image compression can reduce the bandwidth required for image transmission in a network and the storage space of a device, which is of great value in improving network efficiency.
