This function estimates the multifractal indicators of an image. It takes as input a class object "leader" and a range of scales and returns a vector containing hmin, c1 and c2 .

(Package: wmlf) :
Displays the scales indicators to estimate hmin , c1 and c2
Displays graphics to choose the range of scales for estimating hmin, c1 and c2. If the analysis is limited , this function only displays the graph of the logarithm of the maximum wavelet decomposition by scales. If this curve is descending, it is essential to integrate the image.
This function calculates the wavelet decomposition leaders of a square matrix . Concretely , the output function returns a 'Leader' class object that allows calculations hmin , c1 and c2 . These indicators can then be used to discriminate, classify, study the image.
