Welcome to the IMAGERS website, where you will find information about our image processing research group at UCLA. Our general research area is in mathematical modeling and computational techniques for image processing, especially using Partial Differential Equations. IMAGERS is part of the UCLA Mathematics Department and the Institute of Pure and Applied Mathematics, and collaborates with lots of other departments such as Computer Science Department and the School of Medicine. Our research has been supported by the Office of Naval Research (Grant #N00014-06-1-0345), the National Science Foundation (Grants #CCF-0528583 and #GEO-0610079) and National Institutes of Health (Grant #U54 RR021813).
