Abstract
In order to analyze an image, a search is made, for all the minima of the image, for the dynamic of these minima. When the dynamic of these minima is small it corresponds finally to noise. If this measured dynamic is large, the minimum is regarded as being representative of a sufficiently significant irregularity in the image signal.
