ITR: 3D Free Form Models for the Representation, Manipulation, and Recovery of Shape, with Applications to Archaeology and Virtual Sculpting

从非结构化传感器数据中进行3D形状表示、分析、处理和估计的问题不仅是计算机视觉的核心，而且对几何建模、计算机图形学、计算几何、医学成像、监视等也具有重要意义。这个建议的目的是在解决考古学中某些关键问题的背景下研究解决这些问题的方法。 该应用领域提供了以下三个明显的优点：（i）它是自由形式形状的丰富来源，例如，陶器碎片、大理石板和浮雕、雕塑、柱头、建筑立面等，这是很容易获得的，在对比的3D自由形式的形状从医学图像，需要专家分割;此数据也更丰富，更多变的数据比在一个典型的制造设备;（ii）的问题是一个genericnature和所提出的方法可以应用到各种其他domains;（iii）这一应用领域形成了物理科学和人文科学之间的关键桥梁。

The problems of 3D shape representation, analysis, manipulation,and estimation from unstructured sensor data are central not onlyto computer vision, but are also of key significance to geometricmodeling, computer graphics, computational geometry, medical imaging,surveillance, among others. The goal of this proposal is to investigateapproaches to these problems in the context of tackling certainkey problems in archaeology. This area of application offersthe following three distinct advantages: (i) it is a rich sourceof free-form shapes, e.g., pottery sherds, marble plates and reliefs,sculpture, column capitals, building facades, etc., which areeasily accessible, in contrast to 3D free-form shapes obtainedfrom medical images which require expert segmentation; this datais also richer and more variable than data available in a typicalmanufacturing environ-ment; (ii) the problems are of a genericnature and the proposed approaches can be applied to a varietyof other domains; (iii) this application area forms a key bridgebetween the Physical Sciences and the Humanities.
