摘要
We consider edge-enhancing operators employing a modification of the Laplacian called the order statistic (OS) Laplacian. The edge-enhancing operators are evaluated for their performance on the convex/concave (C/C) edge, which is a useful blurred edge model, and on white Gaussian noise input signals. It is shown that the operators employing the OS Laplacian are much less sensitive to noise than the edge-enhancing operator employing the Laplacian, while the edge-enhancing characteristics of the former are comparable to those of the latter. One set of images processed by these operators is presented to illustrate the performance characteristics of these operators. © 1990 IEEE
