Abstract—In this paper, a new method of image edge-detection and characterization is presented. “Parametric Filtering method ” uses a judicious defined filter, which preserves the signal correlation structure as input in the autocorrelation of the output. This leads, showing the evolution of the image correlation structure as well as various distortion measures which quantify the deviation between two zones of the signal (the two Hamming signals) for the protection of an image edge. Keywords—Edge detection, parametrable recursive filter, autocorrelation structure, distortion measurements. I.
