Abstract

Consistency algorithms are used to reduce the overall computation time for consistent labeling problem which is commonly used in computer vision. We have given parallel algorithms to enforce arc consistency, which has been shown to be inherently sequential[3,6]. Since all three parallel algorithms have the same time complexity on a PRAM, it is necessary to implement them on a parallel processor to determine which one performs best. The results of implementing them on a BBN Butterfly are presented here.
