Tracking of tissue in the surgical environment is often done via locating frame-to-frame keypoint correspondences, and then using these correspondences to warp a prior underlying model such as a spline, mesh, or embedded deformation. We introduce a novel learned model which takes keypoint correspondences as input and enables a prior-free estimation of deformation at any location. For fast point tr...
