             abstract = "The watershed transform have been used for image segmentation 
                         relying mostly on image gradients. However, background noise tends 
                         to produce spurious gradients, that cause over-segmentation and 
                         degrade the output of the watersheds transform. Also, low-contrast 
                         edges produce gradients with small magnitudes, which may cause 
                         different regions to be erroneously merged. In this paper, a new 
                         technique is presented to improve the robustness of watersheds 
                         segmentation, by reducing the undesirable over-segmentation. A 
                         redundant wavelet transform is used to denoise the image and 
                         enhance the edges in multiple resolutions, and the image gradient 
                         is estimated with the wavelet transform. The watersheds transform 
                         is then applied to the obtained gradient image, and segmented 
                         regions that do not satisfy specific criteria are removed.",
