What is Subband Coding for CCD Image Compression about?

This paper presents a subband coding technique for compressing images from single-CCD cameras with Bayer color filter arrays. The technique applies a symmetric short kernel filter horizontally and vertically to the red and blue color signals, and a two-dimensional perfect reconstruction filter to the green signals. It is designed to compress the raw image data directly from the CCD before color processing in order to simplify circuit logic. Simulation results show it offers better image quality than DPCM or
