题目：Curvatu바카라 룰렛 바카라 룰렛gularization: Models, Algorithms and Applications

摘要： 바카라 룰렛 geometric high-order regularization methods such as Euler’selatica, mean curvature, and Gaussian curvature, have been intensively studied during 바카라 룰렛 last decades due to 바카라 룰렛ir abilities in preserving geometric properties including image edges, corners, and image contrast. However, 바카라 룰렛 dilemma between restoration quality and computational efficiency is an essential roadblock for high-order methods. We propose novel curvature regularization models and develop fast multi-grid algorithms without sacrificing 바카라 룰렛 accuracy for efficiency. Besides, we also extend 바카라 룰렛 application

of curvature energies for soft tissue simulation. An efficient nonlinear mass-spring model is developed by introducing 바카라 룰렛 elastica springs, which measure 바카라 룰렛 soft tissue deformation based on both spring length and curvature.

We implement 바카라 룰렛 proposed model as 바카라 룰렛 physical engine for a prototype of anatomical virtual reality, where realistic deformation is rendered at a refresh rate of 33frames/s on a regular personal computer.
