Fine grain image computations on electro-optical arrays

A set of array processors with optical interconnection networks for fine grain image processing is considered. The unit-time interconnection made possible with the use of free-space optics results in efficient solutions to communication-intensive image computations. Using these models, a summary of results in designing O(log N) pointer-based algorithms for several tasks in low- and medium-level vision are presented, along with a generic subroutine that can be used to simulate algorithms for image computations on the proposed electro-optical arrays
