Abstract

In this paper, we address the problem of rotation invariance in edge detection. The sensitivity of first order edge detectors in edge orientation is examined. It is shown that the rotation invariance property of an edge detector has no precise consequences on its performance. There are rotationally symmetric (resp. rotationally dependent) detectors the performances of which are edge orientation sensitive (resp. orientation free) and vice-versa. Furthermore, we present the performance evaluation of the Canny and Deriche detectors.
