Cardiac Trabeculae Segmentation: an Application of Computational Topology (Multimedia Contribution) Chen, Chao Metaxas, Dimitris Wang, Yusu Wu, Pengxiang image segmentation trabeculae persistent homology homology localization In this video, we present a research project on cardiac trabeculae segmentation. Trabeculae are fine muscle columns within human ventricles whose both ends are attached to the wall. Extracting these structures are very challenging even with state-of-the-art image segmentation techniques. We observed that these structures form natural topological handles. Based on such observation, we developed a topological approach, which employs advanced computational topology methods and achieve high quality segmentation results.
