摘要
Image pixel values in a mosaiced sampling pattern (such as that generated by a Bayer color filter array) are mapped into four color channels that correspond to rectangular sampling patterns. In one embodiment, the transformation from the original mosaic-patterned pixels into the new four-channel color space can be made reversible in integer arithmetic. That allows for the implementation of efficient lossless image compression systems for mosaiced (e.g., raw, or raw Charged Couple Device (CCD)) images.
