A Fast Multiscale Edge Detection Algorithm Based on a New Edge Preserving PDE Resolution Scheme
Résumé
In this communication we present a new explicit numerical scheme to approximate the solution of the linear diffusion filtering. It allows to introduce a new edge preserving scheme which is fast, stable, easy to program and applicable to any dimensions. Our diffusion scheme is then put into a simple and original multi-scale edge detection algorithm. Some experimental results of the proposed approach for the multi-scale detection of edges in greyscale images are presented, as well as a comparison with other diffusion filtering schemes.
