Paper Abstract

A new prediction technique using luminance compensation with adaptive block size for multispectral image compression is proposed. The luminance compensation which is a function approximation technique is updated block by block for efficient coding. Existing compression techniques do not exploit the property that the spatial features of neighboring spectral bands are almost identical. In other words, the image content of each band usually has almost the same spatial shape even when the pixel values are different. The approach proposed here is a novel scheme that takes advantage of the relationship of almost identical spatial feature between bands. It is a prediction scheme based on the luminance compensation between neighboring spectral bands.
