研究领域

My research background is in the field of computer graphics and computer vision. I am particularly interested in developing mathematical / statistical models that describe the shape of 3D objects and how the shape of 3D objects varies across a population. This is a fundamental problem and a building block to many applications in biology, medical imaging, and computer graphics. The mathematical models are then used for (1) correspondence and registration, (2) 3D modelling, synthesis and animation, and (3) 3D reconstruction. Since 2012, I am also working on image processing techniques for image-based phenotyping of cereal plants grown in different environments ranging from controlled ones (e.g. laboratory experiments) to large fields as done by farmers and breeders. We developed expertise using various types of sensors and platforms ranging from hand-held cameras to sensors mounted on drones.
