Abstract

A two-layer image coding method compatible with JPEG XS is proposed. JPEG XS is a new international standard for still image coding that has the characteristics of very low latency and very low complexity. However, the image quality is saturated at a certain quality level in general, although JPEG XS compression may be able to achieve visual lossless coding. The proposed method has a two-layer structure similar to JPEG XT, which consists of JPEG XS coding as the base layer and the extension layer. In an experiment, the proposed coding is demonstrated to outperform JPEG XT in terms of the coding efficiency, while maintaining compatibility with JPEG XS.
