00400 Minsky and Papert argue that vision is a prime problem area for
00500 the study of intelligence. They see the main problems as the description
00600 of data and procedures to represent a variety of kinds of knowledge. This
00700 knowledge we now conceive of in terms of microtheories, well worked out
00800 systems of knowledge in small domains such as topology, geometry, chemistry,
00900 biology, psychology and human relations. We come to see the problem as
01000 implementing these microtheories as the semantics of particular domains.
01100 The most important microtheories of vision are related to representations.
01200 Two representations help us with problems like:
01300 how do we describe a complex object
01400 how do we relate a scene just after moving our head to that
01500 just before.
01600 These are the representations of shape and space. As problem areas,
01700 the microtheories of vision are relatively well-defined, since they
01800 are derived from models of topology and geometry, and properties of the
01900 physical world. Some of the complication of social and psychological models
02000 does not widely enter in vision.
02100
02200 Some areas which have been attacked have been:
02300 theoretical understanding of line-drawings Huffman,Clowes,Waltz
02400 structural learning Winston
02500 use of world model for outdoor scenes Yakimovsky
02600 representation of complex objects Binford,Agin,Nevatia
02700 computational geometry-computational complexity
02800 There is a great need and opportunity for work in perceptual strategies
02900 which has the advantage of a well-defined problem domain for which we
03000 have great intuition, so that we can use semantics to do otherwise very
03100 hard problems. There is also a need for good systems work.
03200
03300 This is an applications area with promise. We have a serious effort in
03400 programmable automation. The application area is a source of good problems
03500 in AI at this stage. We hope that more support for AI will come from the
03600 realization of the impact of these techniques on problems outside the
03700 university.
00100 using our representation of complex objects, describe a few objects for
00200 example, pump base

00400 extend the ideas of Huffman and Clowes with dual graphs (see Mackworth))
