An Efficient Method for Projection-Based Image Deblurring
E. Sambasiva Rao, S. M. Afroj · 2012
Previously lot of problems are encountered in image processing – image deblurring. From the origination of the image deblurring to its broad applications in enormous number of areas today, the deblurring approaches have evolved with time and forked into many different and fascinating branches. In this paper, we propose a method for reducing out-of-focus blur caused by projector projection. We estimate the Point-Spread-Function (PSF) in the image projected onto the screen by using a camera that captures the projector screen. According to the estimated PSF, the original image is pre-corrected, so that the projected image can be deblurred. Proposed system can successfully reduce the effects of out-offocus projection blur, even though the screen image includes spatially varying blur without projecting the feature image.
