Abstract
Deep neural network-based methods are becoming popular for disease diagnosis and treatment in Endoscopy. In this paper, we discuss our submission to Endoscopic Artefact Detection Challenge (EAD2020). The competition is part of grand challenges in Biomedical Image Analysis and consists of three sub-tasks1: i) Bounding box-based localisation of artefacts ii) Region-based segmentation of artefacts, and iii) Out of sample generalisation task. For the first sub-task, we modify the Faster R-CNN object detector by integrating a powerful backbone network and a feature pyramidal module. For the second sub-task, we implemented a U-Net based autoencoder with a modified loss function to construct the semantic channels. For the third sub-task, we used ensembling techniques along with a data-augmentation technique inspired by RandAugment to boost the generalisation performance. We report a Scored of 0.1869 ± 0.1076 for the first task, sscore of 0.5187 with a sstd of 0.2755 for the second task and mAPg of 0.2620 and a devg of 0.0890 for the third task on the test data-set. Our method for the third task, achieves the third position on the leaderboard for the mAPg metric and also surpasses the results obtained by many methods in the previous EAD2019 challenge.
