The proposed algorithm is based on nonlinear derivatives to automatically select the best edge information. This algorithm can replace the classical derivative with the following benefits:- univocal edge localization for synthetic and real images- noise reduction with no regularization: the noise level is weaker that the noise level in the original image- better direction estimation of the gradient- can product a confident edge reference map with synthetic images- extremely efficient on salt noise OR pepper noise (this last case needs a change in the nonlinear derivatives)- still noise reduction with regularized schemes (Canny, Demigny, ...)- can also be adapted to the asymetrical filters (Prewitt, Sobel, ...).These nonlinear derivatives can also be advantageously used in 1D and nD signals.Drawback: no detection of vertical and horizontal "white" thin (1 pixel) linesRk: this demo only performs edge detection and does not include edge extraction (local maxima) and other steps to obtain a binary edge map.Ref: A Nonlinear Derivative Scheme Applied to Edge Detection, Olivier Laligant, Frederic Truchetet, IEEE Transactions on Pattern Analysis and Machine Intelligence - PAMI , vol. 32, no. 2, pp. 242-257, 2010
