An H.261-Compatible Fuzzy-Controlled Coder for Videophone Sequences

A. Leone and A. Bellini and R. Guerrieri


In this work we describe an H.261-compatible coder with fuzzy control of the quantization parameters. The quantization parameters are evaluated in order to minimize perceptual distortion and to transmit the images at a fixed bit rate. The fuzzy controller classifies the different areas of the picture according to a set of 28 fuzzy rules using features related to temporal and spatial activity of the sequence. Experimental results show a higher perceptual quality of the new technique when compared to a customary methodology based on the buffer fullness control.
