Computer Vision
- Image Restoration/Enhancement:
Images are often subject to quality degradation such as blurring and noise. Using statistical models
of natural images, we have developed a series of methods to restore the degraded image to better
qualities.

- Object Tracking:
Tracking multiple moving objects in videos is an important task in computer vision and is an important part
of video analysis system. We have developed novel multi-object tracking methods based on hypergraphs.
