Abstract : We present a low complexity algorithm for lossless compression of color mosaic images generated by Bayer CCD color filter array. This algorithm is based on an interesting use of integer wavelet transform followed by a fast adaptive context-based Golomb-Rice coding. The lossless compression performance of the proposed algorithm is apparently the best reported in the literature so far for color mosaic images.
