Segmentation of Melanoma Skin Lesion Using Perceptual Color Difference Saliency with Morphological Analysis

Algorithm 1

Input:    color image.

Output:   grayscale saliency map,   silhouette saliency map.

It is assumed that the standard color difference formula described by equations (10) to (17)

has been implemented to be invoked in the computation of a saliency map in step (12)

of this algorithm.
