ABSTRACT:
A system and method for compressing and decompressing multi-spectral images in two color spaces is provided. The system and method employ the transformation, compression and reconstruction of color space components from which difference data between the original color space components and the reconstructed color space components may be derived. A compressed data stream including compressed color space data and compressed difference data in a another color space is generated. The difference data may be utilized to reconstruct a lossless or near lossless image of the original.
