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.
