MODELING BRIGHTNESS PERCEPTION AND SYNTACTIC IMAGE-CODING

We present a study concerning the realizability of a syntactical image coding scheme for the modeling of brightness perception. This scheme is based on a multiscale Gabor analysis, a symbolic line and edge repr esentation, additional low-pass channels, and nonlinear amplitude tran sfer functions. It is shown that this scheme, although not optimized, can already predict various brightness effects such as illusions. Alth ough only studied in the 1-D static case, and without going into detai ls concerning quantization effects, we argue that such a brightness mo del may be advantageous in digital image coding applications.
