Dissecting Self-Supervised Learning Methods for Surgical Computer Vision

1 code implementation1 Jul 2022 Sanat Ramesh, Vinkle Srivastav, Deepak Alapatt, Tong Yu, Aditya Murali, Luca Sestini, Chinedu Innocent Nwoye, Idris Hamoud, Antoine Fleurentin, Georgios Exarchakis, Alexandros Karargyris, Nicolas Padoy

Correct transfer of these methods to surgery, as described and conducted in this work, leads to substantial performance gains over generic uses of SSL - up to 7% on phase recognition and 20% on tool presence detection - as well as state-of-the-art semi-supervised phase recognition approaches by up to 14%.

Unsupervised domain adaptation for clinician pose estimation and instance segmentation in the operating room

1 code implementation26 Aug 2021 Vinkle Srivastav, Afshin Gangi, Nicolas Padoy

Second, to address the domain shift and the lack of annotations, we propose a novel unsupervised domain adaptation method, called AdaptOR, to adapt a model from an in-the-wild labeled source domain to a statistically different unlabeled target domain.

Neuro-Endo-Trainer-Online Assessment System (NET-OAS) for Neuro-Endoscopic Skills Training

no code implementations16 Jul 2020 Vinkle Srivastav, Britty Baby, Ramandeep Singh, Prem Kalra, Ashish Suri

The objective of the current study was to develop a modified version (Neuro-Endo-Trainer-Online Assessment System (NET-OAS)) by providing a stand-alone system with online evaluation and real-time feedback.

Face Detection in the Operating Room: Comparison of State-of-the-art Methods and a Self-supervised Approach

no code implementations29 Nov 2018 Thibaut Issenhuth, Vinkle Srivastav, Afshin Gangi, Nicolas Padoy

Methods: We propose a comparison of 6 state-of-the-art face detectors on clinical data using Multi-View Operating Room Faces (MVOR-Faces), a dataset of operating room images capturing real surgical activities.
