Image Processing Lab (IPL) is a research laboratory at Sharif University of Technology for advanced technologies in image and video processing, in affiliation with the Department of Computer Engineering. It is directed by Professor Shohreh Kasaei. Current research projects include computer vision, object recognition, automatic surveillance and object tracking, object–based video compression, error concealment, E-learning, image segmentation, biometric authentication, hyper-spectral image analysis, and content-based image retrieval. While the emphasis is on applied research, we are also studying a number of issues of theoretical importance. Description of both current and recent research projects can be found by following the Research Tab.
