This paper presents a novel blind motion deblurring method for dealing with non-uniform blurs caused by camera shakes. While there are recent works for non-uniform motion deblurring [Whyte et al. 2010; Joshi et al. 2010], those approaches either limit the freedom of camera motions or require special hardware. Our method is based on a novel representation of motion blurs, which models the blur effects using a set of homographies [Tai et al. to appear]. This representation can fully describe the motions of camera shakes in 3D world, which cause non-uniform motion blurs. Our main contribution is the blind motion deblurring algorithm associated with this representation. We solve the ill-posed non-uniform point spread function (PSF) estimation problem by transforming it into a well-posed image registration problem that estimates homographies. To improve the robustness of our method, we use two input images for deblurring. Our method is experimented with both synthetic and real world examples, and produces superior deblurring results compared to previous methods.
