Dr. Crispell received his BS from Northeastern University in 2003 and Ph.D. from Brown University in 2010 where he focused on probabilistic 3D reconstruction algorithms using volumetric geometry representations. Dan is a co-founder of Vision Systems and has published several research papers in the fields of 3D reconstruction, image and video registration, and change detection. He has developed and applied 3D reconstruction and automatic change detection processing techniques to overhead imagery and developed automatic fusion and exploitation algorithms for LIDAR, image, and video data. He has implemented a belief propagation framework for inferring 3D scene representations of single images based on fusion of outputs from a large set of independent off-the-shelf computer vision algorithms as part of the DARPA Visual Media Reasoning (VMR) program. Current areas of investigation also include the use of 3D models to aid in the human face recognition task.
