A Design Method for Golomb Coding in Layered Scrambled JPEG XS Scheme

In this paper, we propose two-layer lossless coding compatible with JPEG XS that can process in the scrambled domain. For encoding scrambled residuals of the enhancement layer, we introduce a design method for Golomb coding. Efficient Golomb coding can be achieved by setting a coding parameter on the basis of a base-layer JPEG XS parameter. Lightweight and efficient encoding can be realized without additional pro-cessing for coding parameter optimization. We demonstrated its performance via simulation for 8K ultra-high-definition images.
