Abstract
Laplacian operators used in the literature for digital image processing are not rotationally invariant. We examine the anisotropy of 3 x 3 Laplacian operators for images quantized in square pixels, and find the operator which has the minimum overall anisotropy.Year: 1999 PMID： 18267421 DOI： 10.1109/83.791975
