However, classifying a polyp as being neoplasm or not and segmenting it at the pixel level is still a challenging task for doctors to perform in a limited time. In this work, we propose a fine-grained formulation for the polyp segmentation problem. Our formulation aims to not only segment polyp regions, but also identify those at high risk of malignancy with high accuracy. In addition, we present a UNet-based neural network architecture called NeoUNet, along with a hybrid loss function to solve this problem. Experiments show highly competitive results for NeoUNet on our benchmark dataset compared to existing polyp segmentation models.","url_abs":"https://arxiv.org/abs/2107.05023v1","url_pdf":"https://arxiv.org/pdf/2107.05023v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[],"tasks":[{"task_slug":"medical-image-segmentation","task_name":"Medical Image Segmentation"},{"task_slug":"segmentation","task_name":"Segmentation"}],"methods":[],"datasets_introduced":[{"slug":"bkai-igh-neopolyp-small","name":"BKAI-IGH NeoPolyp-Small","full_name":""}],"methods_introduced":[],"results":[{"leaderboard":"/sota/medical-image-segmentation-on-bkai-igh","task":"Medical Image Segmentation","dataset":"BKAI-IGH NeoPolyp-Small","model":"NeoUNet","rank_in_archive_order":5,"of":9,"metrics":{"Average Dice":"0.80723"},"uses_additional_data":false}],"syntology":{"atlas_url":"https://app.syntology.ai/?focus=2107.05023","mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
