报告题目：Spectral Geometry of Shapes

主持人：何晖光（中国科学院自动化研究所）

报告摘要： Shape analysis is a fundamental problem in many research fields such as computer graphics, computer vision, image analysis, robotics, and so on. The increasing 3D shape data demands a variety of shape analysis methods. Nevertheless, 3D shape analyses based on Euclidean transformations suffers many variance problems. This talk will present shape analysis approaches based on shape spectrum in differential geometry. The shape spectra contain the intrinsic geometry information of a shape and reveal the relationship across shapes, therefore, they are able to facilitate a variety of 3D shape analyses in a single uniform framework. We prove the shape spectrum is a continuous function to a scale function on the conformal factor of the manifold. The derivatives of the eigenvalues are analytically expressed with those of the scale function. The property extends the shape spectra across isometric and non-isometric deformations. This talk also demonstrates several exemplar applications of using the shape spectrum-based methods for solving real-world problems.
