My research interests are mostly in the field of digital image and video processing, and include blind image restoration from motion and atmospheric effects, medical image processing, feature extraction, super-resolution, automatic image quality assessment, target acquisition (by observers and automatically), human vision, vision-oriented image processing, and automobile night-vision.

Projects with demonstration of results, in image and video processing

·        Blind Image Restoration, Given a Single Unknown Motion-Blurred Image 

·        Super-Resolution Reconstruction of Staggered TDI Motion-Degraded Video (space-variant distortions, thermal imaging system)

·        Moving Target Acquisition (by observers) in Long-Range Imaging (with and without image restoration)

·         Automatic Moving Target Acquisition (detection & tracking)  in Long-Range Imaging (with and without image restoration)

·         Interactive Blind Restoration of Images Degraded by Motion  (Can be activated only from within Ben Gurion University)
