摘　　要：提出一种用于改善算法效率和鲁棒性的多分辨率图象匹配方法，在该方法中我们设计了一个新颖的与基于个人计算机的图象处理系统联用的金字塔计算结构，用以加速系统计算速度。与单纯由ＰＣ机驱动的图象处理相比，该系统的处理速度提高了一个数量级。这种基本的金字塔结构还可用作建立更大规模的金字塔结构的＂砖石＂．本文还对该金字塔结构的性能作了分析。In this articld a multiresolution image method is proposed to improve the efficiency and robustness of algorithms. In the method, a novel pyramid - like parallel computing architecture which cooperates with a personal computer based imge processing system is designed to accelerate the computations. The system gains an operational speeding - up by a factor of about 10 as compared with an image processing systme driven merely by a PC. These essential pyramidal computing structures can be used as 'bricks' to construct a pyramidal architecture of larger scale. The analysis of the performance of the essential pyramidal computing structure is also carried out.
