Research on segmentation and edge refinement of melanoma image
Segmentation of melanoma image has important clinical value in the diagnosis and treatment of skin diseases.However,due to the lack of annotation and serious category imbalance of data set,the accu-racy of the segmentation map is low and the edge is rough.Therefore,a melanoma segmentation and edge refinement method is proposed,which can be implemented in three stages.In the first stage,after classif-ying the melanoma data set,multiple hierarchical class activation maps are extracted and processed by weakly supervised method.In the second stage,a UNet model is built to segment malignant samples in melanoma data set.In the third stage,the edge refinement of the results of the second stage is carried out by using the enhanced and overlaid class activation map obtained in the first stage.Experimental results on the ISIC melanoma dataset show that after three stages of processing,the segmentation map has finer ed-ges,with a mean intersection over union value of 86.04％,a Dice similarity coefficient of 0.937,and a Jaccard similarity coefficient of 0.885.
