DTC Leading Edge Seminar Series

Capture and Processing of Sharp Images of Moving Objects


Scott McCloskey

Wednesday, September 22, 2010
3:30 p.m. reception
4:00 p.m. seminar

401/402 Walter Library

This talk concerns the capture and processing of sharp images of moving objects using a computational photographic technique known as the fluttering shutter, and summarizes two papers presented at this year’s European Conference on Computer Vision (ECCV). We extend the flutter shutter capture work of Raskar, et al. by first demonstrating that a given shutter sequence has a limited range of velocities over which it produces invertible motion blur, and then by proposing an algorithm to find velocity-specific sequences. In order to enable a fully-automated flutter shutter system, we further present the first automatic blur estimation technique which is applicable to coded exposure images, and demonstrate its effectiveness over a range of motion types: constant velocity, constant acceleration, and periodic motion. Finally, the talk will demonstrate the utility of flutter shutter image capture to a specific image exploitation task: iris capture for biometric identification.


Scott McCloskey joined Honeywell’s Integrated Security Technology section in 2007 as a Computer Vision Research Scientist, and has since served as the principle investigator for several government-funded projects from DARPA, IARPA, and the Biometrics Task Force (BTF). His research interests include computational photography, computer vision, and biometrics. Dr. McCloskey received his PhD in Computer Science from McGill University in 2008, a MS in Computer Science from the Rochester Institute of Technology in 2002, and a BS in Computer Science and Math from the University of Wisconsin-Madison in 1998. He is the author of several peer-reviewed conference papers including recent work at CVPR, ECCV and ICCV. As an active part of the computer vision research community, Dr. McCloskey has served as a panelist for the National Science Foundation (NSF), on the program committee for the IEEE Workshop on Applications of Computer Vision, and as reviewer for numerous conferences and journals.
