Abstract :
This paper presents a method for enhancing the gray level images. This method takes part from the category of point transforms and it is based on interpolation functions. The latter have a graphic represented by piecewise linear functions. The interpolation nodes of these functions are calculated taking into account the statistics of gray levels belonging to the image.
