摘要
介绍了一种改进Laplacian阶跃边缘检测算子。它类似于传统的Laplacian算子,但用x和y的最大值代替了两者之和。将两种算子作用于一组实验图像,并对检测的结果进行了比较。
The note describes an improved operator that responds to step edges, but not to ramps. It is similar to the digital Laplacian, but uses max, rather than the sum, of the x and y second differences. The output obtained from the operator applied to a set of test pictures are compared with each other and with the standard digital Laplacian.
