JPEG XS Standard (ISO/IEC 21122) for Lightweight, Low-Latency Image Coding

At its 94th meeting, ISO/IEC SC29WG1 (aka. JPEG committee) decided to create a third edition of the JPEG XS standard (ISO/IEC 21122) for lightweight, low-latency image coding. While existing coding tools already support the compression of natural content and CFA RAW Bayer pattern data well, this third edition will extend the previous editions with coding tools that improve its performance on compression of screen content and static background sequences. — First experiments demonstrate that the proposed coding tools can improve the average PSNR performance of JPEG XS on such sequences more than 10dB, and approximately 3dB on computer generated content. In this work, authors will present the proposed coding tools and will evaluate their performance objectively by PSNR.
