“…The PCDS algorithm is qualitatively and quantitatively compared to the spatially weighted dissimilarity (SWD) [77], principal component analysis (PCA) [78], Markov chain (MC) [79], and saliency based skin lesion segmentation (SSLS) [17] which are benchmark saliency segmentation algorithms. In addition, we establish comparison with the Otsu algorithm [71], -means clustering [80], fuzzy -means (FCM) clustering [81], and modified JSEG [12] which are benchmark nonsaliency segmentation algorithms.…”
