Lung image segmentation and vision-based navigation for interventional bronchoscopy

Mali Shen, Guang-Zhong Yang, Pallav Shah, Imperial College London
2020
Furthermore, automatic fi ssure segmentation is explored by adopting a surface growing approach based on Bayesian network and fully convolutional neural networks.  ...  Navigation systems have been studied to assist camera localisation either with video-CT registration or electromagnetic tracking. Video-CT registration is favoured due to easy setup and low cost.  ...  Furthermore, data augmentation techniques [137] enable training some small networks, such as U-Net, from scratch.  ...
