176 An approach to three-dimensional scene databasesCurrent image database research is concerned for the most part with the encoding and processing of two-dimensional images. However, the most successful approach to computer vision is based on 3-dimensional information, organized as either stacks of 2-D images (e.g., the intrinsic images of Barrow an...Image databases; Three-dimensional; Scene databases1987
177 Workshop on multisensor integration in manufacturing automationMany people helped make the Workshop a success, but special thanks must be given to Howard Moraff for his support, and to Vicky Jackson for her efforts in making things run smoothly.

183 Performance of arc consistency algorithms on the CRAYThe consistent labeling problem arises in high level computer vision when assigning semantic meaning to the regions of a n image. One of the drawbacks of this method is that it is rather slow. By using the consistency tests, node, arc and path consistency [9], the search space is drastically reduced...Arc consistency algorithms; CRAY supercomputer; Consistent labeling problem1987
