Underlying many techniques of image restortation, quantization, and enhancement is the mathematically convenient, but visually unsuitable distortion measure of squared difference in intensity. Squared-intensity differences has an indirect phenomenological correspondence in a model of the visual system. We have undertaken, therefore, an experiment that(More)
Linear Prediction schemes make a prediction ^ x i of a data sample x i using p previous samples. It has been shown 1, 3] that as the order of prediction p ! 1, there is no gain to be obtained by coding subband samples. This paper deals with the less well understood theory of nite-order prediction and optimal coding from subbands which are generated by ideal(More)
