A Parallel Algorithm and Implementation of Boundary Conversion in Image Processing
图象处理中边界转换的并行算法及其实现

This paper presents a parallel method of converting boundary to region quadtree. The method based on MIMD model has been implemented on DAWN1000 by comparing sequential results with the parallel results. The algorithm can be finished in O((B×logB)/P), where B is the number of chaincodes, and P is the number of processors. The algorithm can be applied widely in image processing, computer graphics, and pattern recognition etc.
