In this paper, we propose a fast approach for motion deblurring from a single blurred image using multiple one-dimensional edges.
Conventional approaches estimate two-dimensional PSF iteratively by using distribution of gradient magnitudes from natural image statistics or frequency-domain constraints on images. However, it causes large amounts of processing time by iterating the process of two-dimensional image and two-dimensional PSF.
We propose a fast approach by estimating PSF at the edges in the blurred image. A clearness image is desired which is equivalent to image with sharpness edge. Our approach is faster than conventional approaches by reducing some complex two-dimensional processes. |
