Adnan Ansar, Ph.D.
Member of Technical Staff
(Full description>>)
Adnan Ansar is a Member of Technical Staff in the Computer Vision group. He received his Ph.D. in Computer Science from the GRASP Laboratory at the University of Pennsylvania in 2001. His research resulted in a novel linear solution of the n-point/n-line pose estimation problem with several advantages over traditional methods and with direct application to use in augmented reality tasks. He also worked on stability issues for uncalibrated structure from motion in the context of critical surfaces. Prior to his switch to Computer Science, he was a Ph.D. candidate in Mathematics specializing in Differential Geometry. Since starting at JPL in 2002, he has worked on calibration (including development of an unsurveyed calibration routine), stereo, landmark detection and recognition, and the pose estimation aspect of various pinpoint landing tasks.
Ph.D. in Computer Science, 2001 (U. Penn.)
M.S. in Computer Science, 1998 (U. Penn.)
