Abstract

A new technique is proposed for LOG (Laplacian Of Gaussian) filtering based on the method using look-up-tables. The authors take advantage of the circularly symmetric characteristic of the LOG filter, then a look-up-table with acceptable size is established. This transforms a large amount of multiplying operations into easy look-up-table operations. At the same time, another mask which can form an adaptive threshold is added to the LOG mask so that the decision whether a edge exists or not from the result of convolution can be made easily. As a result, LOG filtering becomes a method of edge detection in real time.
