Core Concepts
The author argues that predicting and anticipating surgical phases is more valuable than recognizing them in real-time, as it can influence a surgeon's planning. The SuPRA model offers a unified approach for both recognition and prediction, challenging conventional frameworks.
Abstract
SuPRA introduces a novel method that combines recognition and anticipation of surgical phases to enhance intra-operative assistance. The model leverages past, present, and future information to accurately predict upcoming phases while recognizing the current phase. By validating on datasets like Cholec80 and AutoLaparo21, SuPRA demonstrates state-of-the-art performance with high recognition accuracies. The introduction of new segment-level evaluation metrics like Edit Score and F1 Overlap provides a more temporal assessment of segment classification. This multi-task framework aims to improve surgical workflow generation through accurate phase recognition and prediction of future events.
Stats
SuPRA demonstrated recognition accuracies of 91.8% on Cholec80 dataset.
SuPRA showed recognition accuracies of 79.3% on AutoLaparo21 dataset.
