摘要: 研究了保特征散乱数据的曲面重构问题。根据主曲率的差可以刻画图像的棱角特征这一特性,提出了一种新的能量模型。通过变分法,能量得到了新的微分方程,并利用有限元方法求解。试验结果表明,该方法有良好的重构效果,并很好地保持了棱角特征。
关键词: 水平集函数,主曲率,B-样条基
Abstract: The aim of this paper is to reconstruct surface from scattered points while preserving or enhancing sharp features. This goal is achieved by establishing a new energy model according to the difference of the principal curvatures.We derived a nonlinear partial differential ectuation and solved it using the finite-element method for the unknown level set function. Numerical experiments show that the proposed method is effective.
Key words: Level-set function,Principal curvatures, B-spline basis
