This paper describes a parallel algorithm for a line-finding Hough transform that runs on a linearly connected, SIMD vector of processors. The authors show that a high-precision transform, usually considered to be an expensive global operation, can be performed efficiently, in two to three times real time, with only local communication on a long vector. The algorithm also illustrates a decomposition principle that has wide application in algorithm design for large linear arrays. They include a review of straight-line Hough transform implementations.
