摘　　要：作者将盒滤波技术成功的应用于基于灰度立体匹配中的相似性测度的计算和数学形态学中矩形结构元素的处理中 ,算法的复杂性被大幅度的降低 .另外 ,还对盒滤波技术进行了实际应用的改进 ,进一步减少了整个运算的时间 .Box filtering technique is applied to the computing of similarity measurement of intensity based on stereo matching and the processing of rectangular structure element in mathematical morphology, and the computing complexity is greatly reduced. Taking advantage of the relation between calculation of adjacent pixels, box filtering technique can reduce the computing operations. Its main advantage is that it approaches 4 operations for each pixel and is independent of the window size. In addition, this paper improves on the box filtering and reduces the whole time of the computing.
