DIGITAL FORENSICS We are developing mathematical and computational techniques to detect various forms of tampering in photos, videos, audios, and documents. We also study the ability of our visual system to perceptually detect photo manipulation. The Contribution of Statistical Image Differences to Human Rapid Categorization of Natural Scenes is Negligible. BIO I am a Professor and Chair of Computer Science at Dartmouth. Detecting Hidden Messages Using Higher-Order Statistics and Support Vector Machines. My research focuses on digital forensics, image analysis, and human perception. Higher-order Wavelet Statistics and their Application to Digital Forensics. 5th International Workshop on Information Hiding, Noordwijkerhout, The Netherlands, 2002.
I received my undergraduate degree in Computer Science and Applied Mathematics from the University of Rochester in 1989 and my Ph. in Computer Science from the University of Pennsylvania in 1997. Can Shadows and Reflections Help in the Detection of Photo Forgeries? Creating and Detecting Doctored and Virtual Images: Implications to The Child Pornography Prevention Act. IEEE Workshop on Statistical Analysis in Computer Vision (in conjunction with CVPR), Madison, Wisconsin, 2003. [paper] IMAGE ANALYSIS We have developed techniques for discrete multi-dimensional differentiation [2, 3, 7], blind removal of luminance and geometric distortions [4, 5, 6] and the design of steerable filters [8, 9].
Following a two year post-doctoral fellowship in Brain and Cognitive Sciences at MIT, I joined the faculty at Dartmouth in 1999. Society for Applied Research in Memory and Cognition, Syndey, Australia, 2017. TR2004-518, Department of Computer Science, Dartmouth College, October 2004. HUMAN PERCEPTION We study various aspects of the human visual system, including mechanisms governing search and recognition in cluttered scenes [1-21, 24, 28, 31] and a critique of the theory of temporal synchrony for perceptual grouping [22, 23, 25, 30, 32].
