Generative Adversarial Networks based Skin Lesion Segmentation
Skin cancer is a serious condition that requires accurate identification and
treatment. One way to assist clinicians in this task is by using computer-aided
diagnosis (CAD) tools that can automatically segment skin lesions from
dermoscopic images. To this end, a new adversarial learning-based framework
called EGAN has been developed. This framework uses an unsupervised generative
network to generate accurate lesion masks. It consists of a generator module
with a top-down squeeze excitation-based compound scaled path and an asymmetric
lateral connection-based bottom-up path, and a discriminator module that
distinguishes between original and synthetic masks. Additionally, a
morphology-based smoothing loss is implemented to encourage the network to
create smooth semantic boundaries of lesions. The framework is evaluated on the
International Skin Imaging Collaboration (ISIC) Lesion Dataset 2018 and
outperforms the current state-of-the-art skin lesion segmentation approaches
with a Dice coefficient, Jaccard similarity, and Accuracy of 90.1%, 83.6%, and
94.5%, respectively. This represents a 2% increase in Dice Coefficient, 1%
increase in Jaccard Index, and 1% increase in Accuracy
