a A dermoscopy image with skin lesion, b represents a g map obtained using only image gradients, c represents a g map obtained using SVM and 0.5 in Equation 16, d represents a g map obtained using KNN and 0.5 in Equation 16, e represents a g map obtained using geodesic probability map and 0.5 in Equation 16, f represents the edge map obtained by geodesic probability map and 0.7 in Equation 16. Additionally we applied a thresholding on e to make edges stronger
