Abstract

The system PICASSO 2 has been designed for a comparative evaluation of image processing algorithms. In this paper, the system is used to study the stability of edge detection under affine transformations (shifts, rotations and scalings) of the objects being tested. Six edge detectors (by Canny, Rothwell, Heitger, Black, Smith and Iverson) have been applied to the images from PICASSO 2 data set and the outputs were compared using several performance metrics. In particular, our results show the unstable behavior of all six methods on the edges of varying contrast.
