Stereo matching of satellite images with transputers

A demanding problem involving several algorithmic phases with varying degrees of regularity and data dependence is used to show that a network of transputers programmed in OCCAM has all the attributes needed to explore several processing paradigms. Two alternative organizations of the problem on a network of 21 transputers are compared from the standpoints of speed, hardware efficiency, and ease of programming. Two highly parallel implementations of an algorithm that constitutes part of a real-time system to generate terrain relief maps from satellite stereo image pairs have been programmed. An optimum strategy that demonstrates the power of MIMD (multiple instruction, multiple data streams) parallel computing is determined.<
