A rolling shutter motion blurred image captured with Canon 70D DSLR (a,b), the sharp and undistorted output from our RSMD approach (e), and comparisons with conventional uniform (c) and non-uniform (d) blind deblurring algorithms.
Abstract
Although motion blur and rolling shutter deformations are closely
coupled artifacts in images taken with CMOS image sensors, the two
phenomena have so far mostly been treated separately, with deblurring
algorithms being unable to handle rolling shutter wobble, and rolling
shutter algorithms being incapable of dealing with motion blur.
We propose an approach that delivers sharp and undistorted output
given a single rolling shutter motion blurred image. The key to
achieving this is a global modeling of the camera motion trajectory,
which enables each scanline of the image to be deblurred with the
corresponding motion segment. We show the results of the proposed
framework through experiments on synthetic and real data.
