Abstract:

The design and operation of MINOS II are briefly summarized, including the built-in algorithms, the method of weight-changing, and the use of snake-in-the-box codes for treating analog parameters. The design of a 1024image optical preprocessor is discussed in the light of its development from the 100-image preprocessor. An SDS-910 computer was installed to supervise MINOS II when the ultimate objective of this project is reached, the pattern-recognition equipment will be fully integrated into a data-storage and retrieval complex, and this was the first step toward that goal. A discussion is given of the experimental results starting from the early hand-drawn map symbol experiments with the 100-image preprocessor. Corresponding experiments were carried out with the 1024-image preprocessor using edge-detector masks occupying 8 percent of the retinal field, as compared with 50 percent masks in the earlier equipment. A selective-attention experiment is described in detail. This isolated approximately ten map symbols appearing in the field simultaneously, in a manner which would permit them to be correctly categorized if the appropriate pattern-recognition function were provided.
