Rolling shutter super-resolution in burst mode

Capturing multiple images using the burst mode of handheld cameras can be a boon to obtain a high resolution (HR) image by exploiting the subpixel motion among the captured images arising from handshake. However, the caveat with mobile phone cameras is that they produce rolling shutter (RS) distortions that must be accounted for in the super-resolution process. We propose a method in which we obtain an RS-free HR image using HR camera trajectory estimated by leveraging the intra- and inter-frame continuity of the camera motion. Experimental evaluations demonstrate that our approach can effectively recover a super-resolved image free from RS artifacts.
