Poorvi Vora - Image Processing & Security Applications Research
Most of the research in applications of image processing to problems in security was performed while I was at HP (1995-2003), and covers watermarking for authentication and copyright protection [1,3,4,5,10] and counterfeit deterrence [2,8,9,11]. The only exceptions were [7], the outcome of my M.S. thesis, and [6], the first paper by a student I supervised.
