Optical Flow Detection System Using a Parallel Processor NEURO4

摘要

An image recognition system using NEURO4, a programmable parallel processor, is described. Optical flow is the velocity field that an observer detects on a two-dimensional image and gives useful information, such as edges, about mov- ing objects. The processing time for detecting optical flow on the NEURO4 system was analyzed. Owing to the parallel com- putation scheme, the processing time on the NEURO4 system is proportional to the square root of the size of images, while conventional sequential computers need time in proportion to the size.
