Flutter shutter based motion deblurring in complex scenes

Motion blur in images is due to the relative motion between the camera and the moving object. Deblurring is an ill-posed problem due to the loss of spatial high frequencies during the reconstruction. It is well known that in the approach called flutter shutter, the shutter of the camera is opened and closed according to a pseudo-random binary sequence, which preserves high frequency spatial information, thus making the problem well-posed. In this paper, we present the application of motion deblurring in complex scenarios like partial static and dynamic occlusions, deblurring is applied only on the moving object so as not to affect the static background part. We also present the effects of “flutter shutter” code length-blur length mismatch. We have applied the flutter shutter in a virtual fashion where the coded exposure images are obtained by simulation of a high speed camera.
