Abstract
In this paper, we split the region of interest of dermoscopic images of skin lesions in patches of different size and we analyze the impact of the entropy of the patches on patch-based binary classification using a convolutional neural network (CNN). Specifically, we analyze the distribution of entropy amongst the patches and we compare the training time of a classifier on subsets of the data with varying entropy. We find that the classifier converges faster on patches with higher entropy. Our entropy-based analysis is performed on skin lesion images from the ISIC archive.
