Zhen-Liang Ni, Gui-Bin Bian, Xiao-Liang Xie, Zeng-Guang Hou, Xiao-Hu Zhou, Yan-Jie Zhou
2019 arXiv   pre-print
Segmentation for tracking surgical instruments plays an important role in robot-assisted surgery.  ...  In this paper, a novel network, Refined Attention Segmentation Network, is proposed to simultaneously segment surgical instruments and identify their categories.  ...  To overcome the issues mentioned above, a novel network, Refined Attention Segmentation Network(RASNet), is proposed which utilizes attention mechanism for semantic segmentation of surgical instruments  ...

Autonomous Endoscope Robot Positioning Using Instrument Segmentation with Virtual Reality Visualization

Kateryna Zinchenko, Kai-Tai Song
2021 IEEE Access  
To tackle the issue of real-time surgical instrument segmentation for more precise instrument tip localization, we propose the YOLOv3 and ResNet Combined Neural Network.  ...  The real-time prediction of next desired camera location is estimated using segmented instrument's tip locations from endoscope video and surgeon's attention focus given by tracked virtual reality headset  ...  The current state-of-the-art method Refined Attention Segmentation Network (RASNet), combines ResNet-50 pre-trained on ImageNet as encoder and Attention Fusion Module (AFM) [17] .  ...

2020 arXiv   pre-print
While numerous methods for detecting, segmenting and tracking of medical instruments based on endoscopic video images have been proposed in the literature, key limitations remain to be addressed: Firstly  ...  Intraoperative tracking of laparoscopic instruments is often a prerequisite for computer and robotic-assisted interventions.  ...  Furthermore, the authors wish to thank Tim Adler, Janek Gröhl, Alexander Seitel and Minu Dietlinde Tizabi for proofreading the paper.  ...

CAT: Centerness-Aware Anchor-Free Tracker

Haoyi Ma, Scott T. Acton, Zongli Lin
2022 Sensors  
Accurate and robust scale estimation in visual object tracking is a challenging task.  ...  First, the location and scale of the target object are predicted in an anchor-free fashion by decomposing tracking into parallel classification and regression problems.  ...  Acknowledgments: We gratefully acknowledge the support of the NVIDIA Corporation with the donation of the Titan V GPU used for this research.  ...
