Robust rotations between anatomical curves
Proceedings IEEE International Symposium on Biomedical Imaging - Trang 337-340
Tóm tắt
We give a method for estimating the optimal rotation between anatomical curves corrupted by segmentation noise. We formulate the energy function probabilistically and use an annealing algorithm with explicit outlier rejection to stabilize our solution. We also provide methods for a nearly symmetric estimation of the rigid transformation between three-dimensional curve pairs. We evaluate the performance of the algorithm numerically with respect to the energy function and computation time.
