Abstract

Motion blur removal from images sometimes need to estimate spatially-varying point spread functions (PSFs). We address two critical problems in this process. 

• We observe that the simple scheme to partition the blurred images into regions and estimate their PSFs respectively may make small-size regions lack necessary structural information to guide PSF estimation and accordingly propose region trees to hierarchically estimate them.
• Erroneous PSFs are rejected with a novel PSF selection scheme, based on the shock filtering invariance of natural images.

Our framework applies to general single-image and stereo-image spatially-varying deblurring.
