Proceedings of the 1st International Workshop on DIFFerential Geometry in Computer Vision for Analysis of Shapes, Images and Trajectories (DIFF-CV) 2015

This workshop focuses on problems and approaches in computer vision that involve Riemannian geometric computing. Recent interest in this area has resulted in Riemannian geometric principles being applied in problems such as face recognition, activity recognition, object detection, biomedical image analysis, and structure-from-motion to name a few. Besides being mathematically appealing, Riemannian computations based on the geometry of underlying manifolds are often faster and more stable than their classical counterparts. Over the past few years, the popularity of Riemannian algorithms has increased several-fold due to their successful application in many hard computer vision problems (noted above). Some of the mathematical entities that necessitate a geometric analysis include rotation matrices (e.g. in modeling camera motion), stick figures (e.g. for activity recognition), subspace comparisons (e.g. in face recognition), symmetric positive-definite matrices (e.g. in diffusion tensor imaging), and function-spaces (e.g. in studying shapes of closed contours).
