Paper Abstract

In this paper, we propose a method based on the Maximum Likelihood theory for removing the speckle pattern that plagues coherent images. The hypothesis on the speckle effect imply that the maximum likelihood criterion uses only intensity information. The model of the image is based on a lattice of knots corresponding to the vertices of triangles where the gray level of each pixel inside a cell is provided by linear interpolation.
