Abstract
A method for compressing a multi-spectral data stream corresponding to an image for a selected one of transmission, as a limited bandwidth transmission using a predetermined band, and data storage includes steps for dividing the image into pixel blocks P in each of N bands, where both P and N are integers greater than one, selecting one of pixel blocks in one of N bands as an anchor band and computing prediction coefficients for relating intensities of each pixel in each P pixel block in the remaining N-1 bands based on the anchor band. A codec apparatus is also described.
