中文简介: | 我们从没有边界条件的阴影问题中检查形状作为多项式系统。在一般情况下,该视图允许理想多面体对象的完整解决方案。对于一般情况,我们提出了半定规划松弛程序,以及具有有利于边缘折叠的新平滑项的精确线搜索迭代程序。我们使用这种数值技术来检查阴影模糊度。 |
课程简介: | We examine the shape from shading problem without boundary conditions as a polynomial system. This view allows, in generic cases, a complete solution for ideal polyhedral objects. For the general case we propose a semidefinite programming relaxation procedure, and an exact line search iterative procedure with a new smoothness term that favors folds at edges. We use this numerical technique to inspect shading ambiguities. |
