A Shortcut to Compressing Bayer-Pattern Imagery Losslessly

Bayer pattern has been used in most color digital image sensors; FELICS is a smart algorithm to realize lossless compression. This paper does research on the possibility of combining both the characteristics of Bayer and FELICS to eliminate 3-color-channels transformation. After studying the context correlation in Bayer pattern by FELICS theory in an adjusted way, the approach of modifying original FELICS algorithm to suit Bayer pattern has been addressed clearly. With the experimental results, the usage of Bayer version FELICS has been validated at the end of this paper.
