Discrete Riemannian calculus on shape space (C05)

Subject Area Mathematics
Term from 2013 to 2024
Project identifier Deutsche Forschungsgemeinschaft (DFG) - Project number 211504053
 

Project Description

A Riemannian approach to shape spaces with applications in medical imaging, computer vision and computer graphics is studied in this project. At the heart of the matter is a discrete geodesic calculus for which existence and convergence results are proven. A particular focus is on image models with a high-dimensional, local structure description using learned feature vectors or based on filter kernels weighted with sparse weight functions. The discrete calculus will be generalized to measure spaces and combined with optimal transport methods.
