Geometry Processing
Geometry processing is concerned with the acquisition, analysis and manipulation of geometric data. The field is very broad and algorithms aim at improving 3D reconstructions, finding correspondences between objects, shape interpolation, or analysing physical properties of scanned data. Many applications in geometry processing have counterparts in image processing, e.g. object detection, but geometric data poses special challenges in terms of how to formulate mathematical concepts on discretized domains, and choosing the best data structures and shape representations for each application.
Our group is especially interested in 3D geometric data and works mainly in the directions of 3D shape analysis, point cloud processing and inference from 3D data. But our members have worked on a wide range of subtopics, so feel free to reach out to us if you are interested in any geometry processing related topic!
