Abstract
Image segmentation is a crucial part of medical imaging technology. Threshold-based image segmentation is very effective for medical images. A good segmentation helps in correct diagnosis. In this paper, entropy-based thresholding is used for automatic segmentation of hypo and hyperpigmented skin disease. Here threshold values are selected based on Shannon and Gini entropy. A comparison study with Otsu and Fuzzy C-Means (FCM) method is carried out based on rand index (RI) to prove efficiency of entropy-based thresholding. The rand index value indicates that Gini entropy-based thresholding is the best choice for hypo and hyperpigmented skin diseases segmentation.
