论文摘要
形状对应是计算机图形和视觉中的一个基本问题,在各种问题中的应用包括动画,纹理映射,机器人视觉,医学成像,考古学等。在允许形状进行非刚性变形并且只有部分视图的设置中,问题变得非常具有挑战性。为此,我们提出了一种非刚性的多部分形状匹配算法。我们假定给予参考形状及其多个部分经历了非刚性变形。这些查询零件中的每一个都可以被混乱污染,可能与其他部件重叠,并且可能缺少零件或冗余部分。我们的方法同时求解参考模型的分割,以及与零件(子集)密集的对应关系。关于合成和实际扫描的实验结果证明了我们方法在应对这种具有挑战性的匹配方案方面的有效性。
Shape correspondence is a fundamental problem in computer graphics and vision, with applications in various problems including animation, texture mapping, robotic vision, medical imaging, archaeology and many more. In settings where the shapes are allowed to undergo non-rigid deformations and only partial views are available, the problem becomes very challenging. To this end, we present a non-rigid multi-part shape matching algorithm. We assume to be given a reference shape and its multiple parts undergoing a non-rigid deformation. Each of these query parts can be additionally contaminated by clutter, may overlap with other parts, and there might be missing parts or redundant ones. Our method simultaneously solves for the segmentation of the reference model, and for a dense correspondence to (subsets of) the parts. Experimental results on synthetic as well as real scans demonstrate the effectiveness of our method in dealing with this challenging matching scenario.
