Connection Machine Stereomatching

Michael Drumheller

This paper describes a parallel real-time stereomatching algorithm and its implementation on the Connection Machine computer, a new massively parallel computing system. The main features of the algorithm are 1) real-time performance, 2) the full exploitation of the ordering constraint, 3) a representation that easily maps onto a parallel computer architecture, and 4) the ability to efficiently use a variety of matching primitives. Some results, including timings, are shown for both real and synthetic data. Also discussed are the use of color information and some subtle variations of the basic algorithm.

On parallel stereo

Michael Drumheller
Tomaso A. Poggio

We review some of the open issues in computational stereo. In particular, we will discuss the problem of extracting better matching primitives and of dealing with occlusions. Markov Random Field models - an extension of standard regularization - suggest sophisticated stereo matching algorithms. They are, however, ill-suited to efficient, real-time applications. We will conclude reviewing a new simple but fast algorithm implemented by one of us (Drumheller, 1986) on the TMC Connection Machine (TM) computer. Some of its features are: (a) the potential for combining different primitives, including color information; (b) the use of a stronger and new formulation of the uniqueness constraint; and (c) its disparity representation that maps efficiently into the architecture of the Connection Machine computer.
