Abstract :
The authors make a comparison of the state of the art algorithms for snow areas segmentation in optical satellite images. The comparison address the accuracy of the “forward model” used and the informational theoretical aspects characterising the detection/segmentation algorithms. They also, comparatively, introduce and a new approach: the segmentation of the snow cover as ill-posed inverse problem and its solution in the frame of the Bayesian inference
