New AI framework reduces annotation needs for colonoscopy polyp detection

By PulseAugur Editorial · [1 sources] ·

Researchers have developed WSPolypNet, a novel weakly supervised framework designed for polyp localization in colonoscopy videos. This system utilizes a 3D convolutional neural network to generate class activation maps (CAMs) from video-level supervision, identifying potential polyp regions without requiring detailed frame-by-frame annotations. The framework enhances these localization cues through a multi-view strategy and integrates with MedSAM2, which refines segmentation masks based on polyp boundaries. WSPolypNet demonstrates significant improvements in localization accuracy and recall, substantially reducing the need for extensive manual annotation in medical imaging. AI

IMPACT This research could significantly reduce the manual effort required for annotating medical videos, potentially accelerating the development and deployment of AI tools for diagnostics.

    WSPolypNet: Weakly Supervised Polyp Localization in Colonoscopy Videos

    arXiv:2609.08182v1 Announce Type: cross Abstract: Because dense frame-level annotation of colonoscopy videos is costly, we propose WSPolypNet, a weakly supervised framework for polyp localization using only video-level labels. WSPolypNet employs a 3D convolutional neural network …
