Abstract

Digital image archives may store images in either device-dependent or device-independent form, but the latter places more stringent demands on the image capture process. Multispectral image archives can reduce the problems of colour inconstancy associated with trichromatic images. An experimental study was conducted to determine the efficiency of a new method for encoding multispectral images, using three orthogonal basis functions derived from cone fundamentals plus additional principal components. The results indicated that the encoding method gave a good approximation to the original, and that images of reasonable quality could be reconstructed from files compressed by spatial sub-sampling of the components, with an overall compression ratio in the range 20-40.
