Many algorithms for the matching of stereo edges between two images have been proposed, each of which uses constraints to help select valid matches. However, each of these constraints fails in some circumstances. To address this problem, the general support algorithm is proposed for integrating multiple constraints in parallel using a connectionist network. The constraints are implemented using only positive connections between matches. The use of multiple constraints allows each to be implemented more conservatively, thus applying them where they provide the most accurate information. The iterations of the network allow the constraints to interact cooperatively to select the valid matches. A simulation of the network has been developed, and preliminary results on synthetic images are presented.

The project described is concerned with interfacing between the computer knowledge based system and the real world in the areas of speech recognition and image recognition and understanding. At the upper level the system will consist of knowledge processing while the lower levels will consist of preprocessing and feature extraction. The paper discusses hardware and algorithmic aspects of the system. The systems need to operate in near real time and so providing processing power is a key feature of the work.

In view of the wide introduction of the methods and techniques of spatial processing of signals and fields in the framework of the general problem of reducing the redundancy of video information, there is considerable interest in algorithms for the effective coding and reconstruction of images, matched to the features of the perception of images by the eye. algorithms presented in the present paper, and also those presented by the authors in another paper were used to compile programs for the effective coding of images. In particular, the use of preliminary space-time processing in the context of the models of the eye enable one to obtain an improvement in reducing quantization noise in DPCM coders of up to 15 db in a dynamic range of coded signal of 60 db.

A generalized broadcasting feature for mesh-connected computers is analyzed. In the two-dimensional case there are N equals N**1 **/ **2 multiplied by N**1 **/33 **2 processors with broadcasting feature in each row and each column. This multiple broadcast allows parallel data transfers within rows and columns of processors. The proposed architecture is well suited for solution of many problems in linear algebra, imageprocessing, computational geometry, and numerical computations. Fast parallel algorithms based on this architecture are derived. Bounds on the speedups obtainable with multiple broadcast are also derived.
