Abstract

In this paper, a generalization of Shen-Castan and Canny- Deriche filters in a family of edge detector is presented. This family is built on the choice of an exponential model, now well known in edge detection. It is shown that the best detector is theoretically the filter of index 2 of the family obtained. However, each filter presents interesting performances and the choice of one of them depends on the characteristics of the image and the aim pursue. To help this choice the resolution power of the detector called as the separating power is measured. In this way, the compromise between theoretical performances (isolated edge) and practical performances is discussed.
