Shape Analysis

Over the last years, the availability of devices for the acquisition of three-dimensional data like laser-scanners, RGB-D Vision or medical imaging devices has dramatically increased. This brings about the need for efficient algorithms to analyze three-dimensional shapes.

Our research is focused on reliable and efficient methods for the automatic interpretation of non-rigid three-dimensional shapes. In particular, we have been working on novel approaches to Shape Matching and on the design of Feature Descriptors.

Matching

The goal of shape matching is to register corresponding surface regions of two given three-dimensional shapes. This means for example to identify the hands, the feet and the head of two human figures. Once two shapes are registered, one can infer morphs between them. The video shows examples of such morphs, e.g. interpolating between a samba dancer and a hip hop dancer. In each of these example sequences, a registration of the first and the last shape has been computed, all intermediate frames are obtained by linear interpolation. The colors visualize regions which have been identified with each other.

A registration of two shapes can be the building block for measuring similarity of shapes and for performing shape statistics.

Mathematically, the task is to find a mapping from the boundary surface of one shape to the other one. This typically results in a very difficult, highly non-convex optimization problem.

We are currently working on efficient algorithms for shape matching with a focus on geometric consistency guarantees and on global optimization.

Feature Descriptors

The goal of feature descriptors is to characterize each point on an object's surface regarding its relation to the entire shape. The feature vectors of four different points of a cat are shown above.

In our research we aim at feature descriptors which are robust to shape articulations while capturing as much information as possible. A very powerful mathematical tool for this task is the eigendecomposition of the Laplace–Beltrami operator.
