528 Mathews, V. JohnAn optimal design procedure for intraband vector quantized subband codingAbstTact- Subband coding with vector quantization is addressed in this paper. Forming the data vectors from both between and within the subbands is considered. The former of these two schemes is referred to as interband coding and the latter as intraband coding. Interband coder design is relatively ...1995

541 Harrison, Reid R.Analog VLSI implementation of a visual interneuron: enhanced sensory processing through biophysical modelingFlies are capable of rapid, coordinated flight through unstructured environments. This flight is guided by visual motion information that is extracted from photoreceptors in a robust manner. One feature of the fly's visual processing that adds to this robustness is the saturation of wide-fi_x000...1999-01-01
