TeCNO: Surgical Phase Recognition with Multi-Stage Temporal Convolutional Networks

tobiascz/TeCNO 24 Mar 2020

Automatic surgical phase recognition is a challenging and crucial task with the potential to improve patient safety and become an integral part of intra-operative decision-support systems.

Not End-to-End: Explore Multi-Stage Architecture for Online Surgical Phase Recognition

ChinaYi/casual_tcn 10 Jul 2021

To address the problem, we propose a new non end-to-end training strategy and explore different designs of multi-stage architecture for surgical phase recognition task.

Learning from a tiny dataset of manual annotations: a teacher/student approach for surgical phase recognition

camma-public/tf-cholec80 30 Nov 2018

Vision algorithms capable of interpreting scenes from a real-time video stream are necessary for computer-assisted surgery systems to achieve context-aware behavior.

Multi-Task Recurrent Convolutional Network with Correlation Loss for Surgical Video Analysis

YuemingJin/MTRCNet-CL 13 Jul 2019

Mutually leveraging both low-level feature sharing and high-level prediction correlating, our MTRCNet-CL method can encourage the interactions between the two tasks to a large extent, and hence can bring about benefits to each other.

Trans-SVNet: Accurate Phase Recognition from Surgical Videos via Hybrid Embedding Aggregation Transformer

xjgaocs/Trans-SVNet 17 Mar 2021

In this paper, we introduce, for the first time in surgical workflow analysis, Transformer to reconsider the ignored complementary effects of spatial and temporal features for accurate surgical phase recognition.

LensID: A CNN-RNN-Based Framework Towards Lens Irregularity Detection in Cataract Surgery Videos

Negin-Ghamsarian/AdaptNet-MICCAI2021 2 Jul 2021

In particular, we propose (I) an end-to-end recurrent neural network to recognize the lens-implantation phase and (II) a novel semantic segmentation network to segment the lens and pupil after the implantation phase.

xmed-lab/sahc 22 Nov 2021

Automatic surgical phase recognition plays a vital role in robot-assisted surgeries.

Less is More: Surgical Phase Recognition from Timestamp Supervision

xmed-lab/timestamp-surgical 16 Feb 2022

Our study uncovers unique insights of surgical phase recognition with timestamp supervisions: 1) timestamp annotation can reduce 74% annotation time compared with the full annotation, and surgeons tend to annotate those timestamps near the middle of phases; 2) extensive experiments demonstrate that our method can achieve competitive results compared with full supervision methods, while reducing manual annotation cost; 3) less is more in surgical phase recognition, i. e., less but discriminative pseudo labels outperform full but containing ambiguous frames; 4) the proposed UATD can be used as a plug and play method to clean ambiguous labels near boundaries between phases, and improve the performance of the current surgical phase recognition methods.

Free Lunch for Surgical Video Understanding by Distilling Self-Supervisions

xmed-lab/distillingself 19 May 2022

Our key insight is to distill knowledge from publicly available models trained on large generic datasets4 to facilitate the self-supervised learning of surgical videos.

Dissecting Self-Supervised Learning Methods for Surgical Computer Vision

camma-public/selfsupsurg 1 Jul 2022

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. 4% 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%.
