Ideal cross-point regions of prediction errors from LOCO-I algorithm applied to lossless image compression

Abstract

This paper proposes the scheme of ICRICLI (Ideal Cross-point Regions for lossless Image Compression on multiple bit planes with Low complexity lossless compression for Images) that uses cross-point regions with LOCO-I algorithm for optimizing the processing of coding. The scheme ICRICLI is developed from the combination of the improved CRICM (Cross-point Regions for lossless Image Compression on Multiple bit planes) and LOCO-I, it is an algorithm for losslessly encoding and decoding images by optimizing the probability of data bits of the matrix of prediction error in cross-point regions on different bit planes. This scheme can be seen as a proposition of improvement of the standard predictive template of JPEG-LS for losslessly compressing images.
