Repeatability results of the HS dermatologic acquisition system. (a) Gray-scale representation of the two consecutive HS images from the same PSL (Pair1). (b) Gray-scale representation of the two HS images from the same PSL but captured in different spatial positions (Pair2) and binary mask for the segmentation of the PSL pixels (Pair2Masks), where white pixels represent the PSL pixels. (c) Scatterplot of voxel values of Pair1. Repeatability results: $R{D}_{mean}=9.52\%$. (d) Scatterplot of voxel values of Pair2. Repeatability result: $R{D}_{mean}=23.68\%$. (e) Mean and variance of the segmented PSL pixels from Pair2.
