Abstract

One goal in computational photography is to overcome limitations of traditional cameras such as blur. Blur, which is one of the most annoying artifacts in photographs, is caused by long exposure time or lens aberration. Deblurring is a problem to remove blur from a blurry image so that valuable hidden information can be revealed. Deblurring can benefit consumer cameras, medical imaging, aerial and satellite imaging, and many others. In this talk, I will briefly introduce some of our past and recent results in image deblurring including convergence analysis of deblurring, and deblurring in low-light environments. Besides deblurring, I will share my ideas on possible future directions in computational photography research.
