                         images, where each pixel is a 2 X 2 second order tensor, that can 
                         be represented by an ellipse. A proposed tensorial morphological 
                         gradient (TMG) is defined as the maximum dissimilarity over the 
                         neighborhood determined by a structuring element, and is used in 
                         the watershed segmentation framework. Many tensor dissimilarity 
                         functions are tested and other color gradients are compared. The 
                         comparison uses a new methodology for qualitative evaluation of 
                         color image segmentation by watershed, where the watershed lines 
                         of the n most significant regions are overlaid on the original 
                         image for visual comparison. Experiments show that the TMG using 
                         Frobenius norm dissimilarity function presents superior 
                         segmentation results, in comparison to other tested gradients.",
