Abstract
The problem of skin lesion segmentation remains to be a challenging task due to the low contrast of lesions, occlusions and varied sizes of foreground. The existing methods are unable to perform well on complex scenarios. In this paper, an accurate skin lesion segmentation method with Res-SC block and Res-NL block is proposed, which successfully increases the field of view by enhancing the feature representation and aggregating global information. Moreover, a novel loss function is designed, which allows us to focus more on the hard examples and further improve the accuracy rate. On the ISIC 2017 dataset, our method achieves very top performance with (AC of 0.93, DI of 0.88 and JA of 0.80).
