Research in Progress

In terms of basic research, our current focus is the development, of broadly applicable techniques for description and matching of structure in sensory data. Such techniques appear to lmderlie virtually every aspect of early and intermediate vision, such as edge and region finding, perceptual organization and grouping, and the recovery of 3-D shape from contour, texture, stereo and motion They appear to be equally important in other sensory domains, such as audition (e g, for describing the structure in spectrograms.) In particular, we are dealing with the problem of grey-level inspection, and are constructing a vision workbench to allow rapid experimentation with alternative techniques Finally, WC are examining a variety of special-purpose architectures for image processing. These range from a SUN (MC68000-based) workstation, augment,cd with high-speed pipelined VLSI components, to a massively parallel architerture involving a thousand processors and a novel interconnection network.

Brachman Having had experience with knowledge representation syst,ems designed to support "common sense" reasoning, we are developing and implementing a new framework for representation and reasoning in arcas requiring "expertise."
