Explainable Medical Image Segmentation via Generative Adversarial Networks and Layer-wise Relevance Propagation

2 Nov 2021 · Awadelrahman M. A. Ahmed, Leen A. M. Ali ·

This paper contributes to automating medical image segmentation by proposing generative adversarial network-based models to segment both polyps and instruments in endoscopy images. A major contribution of this work is to provide explanations for the predictions using a layer-wise relevance propagation approach designating which input image pixels are relevant to the predictions and to what extent. On the polyp segmentation task, the models achieved 0.84 of accuracy and 0.46 on Jaccard index. On the instrument segmentation task, the models achieved 0.96 of accuracy and 0.70 on Jaccard index.
