Abstract

In this paper; （1）By introducing affine transformation

a direct method based on geometrical moments is presented for edge detection in anisotropic image data.The moments are calculated using the masks of square window in a related isotropic image.And the formulae of edge parameters are deduced.（2） By implying linear interpolation within moments calculation

the operator is improved.A set of non-square masks corresponding to square window are obtained

thus avoiding the time consuming pre-interpolation of image data.（3）Some experiment results about the presented methods are given..
