[Abstract]

Our world consists of various 3D objects with their shape characteristics. 3D shape analysis is a subfield of computer science to explore the inherent geometric attributes of 3D objects. In the application domain, brain shape analysis is one of the popular approaches in neuroimaging studies of brain development and atrophy to understand behavioral or cognitive functions. Despite its importance, the human brain might not be understood well by standard 3D shape analysis techniques due to the anatomical variability accompanied by a complicated, dynamic folding process. In this talk, I will review the challenges in brain shape analysis and introduce my recent surface-based techniques, including brain shape registration and segmentation. I will also discuss how to employ data-driven approaches effectively on insufficient neuroimaging data.
