Abstract:

This paper reports on a preliminary study of applying single-channel scalar and multichannel vector 2-D linear prediction to color image modeling and coding. Also, the novel idea of a multi-input single-output 2-D ADPCM coder is introduced. The results of this study indicate that texture information in multispectral images can be represented by linear prediction coefficients or matrices, whereas the prediction error conveys edge-information. Moreover, by using a single-channel edge-information the investigators obtained, from original color images of 24 bitspixel, reconstructed images of good quality at information rates of 1 bitpixel or less.
