Claim One:
1. A method of processing image data, by reducing image noise, comprising the following steps: a) obtaining points of the image with respective values associated with the points, b) associating a learning zone with a reference point of the image, c) and assigning the reference point new values obtained by a weighted statistical estimation, of weighted mean or weighted median type using the values of the points included in the learning zone, characterized in that it comprises the following steps: c1) for each current point of the learning zone, evaluating a distance characterizing a resemblance between the values of the points in a first window of the image, centered on the reference point, on the one hand and the values of the points in a second window, of the same format as the first window and centered on the current point, on the other hand, c2) and repeating step c1) for all the points of the learning zone in the guise of successive current points by using the distances obtained for all the current points to calculate the weights used in the weighted statistical estimation of step c).
