摘　　要：本文介绍了迭代分块式Hough变换算法,它大大缩短了Hough变换的时间,并用一个实例来说明它的性能,其处理速度约提高24倍,而且重构了原来的图象。这一算法将成为线素提取的有力工具。This paper introduces an iterative block Hough transform algorithm which cuts short greatly the time for Hough transform, and whose performance is demonstrated in an instance. The processing speed is increased about 24 times, and the original image has been reconstructed. The algorithm will become a powerfull tool for extracting lines.
