Ko Nishino

Professor & Associate Department Head for Graduate Affairs

Computer Science

Dr. Nishino is an Professor of Computer Science at Drexel University. Prior to joining Drexel in fall 2005, Dr. Nishino was a postdoctoral research scientist at Columbia University. He received all his degrees from The University of Tokyo: both B.E. and M.E. in Information and Communication Engineering in 1997 and 1999, respectively, and Ph.D. in Information Science in 2002. Dr. Nishino's research interests lie primarily in computer vision, specifically in developing novel models and computational algorithms to better extract, understand, and regenerate visual information from photographs and videos. To this end, his work's main focus centers on leveraging intrinsic structures of visual data -- the latent structures that can be found in the geometry, radiometry, and motion of real-world scenes that are not necessarily apparent to the naked eye.
