In this paper, we develop a modified differential Structure from Motion (SfM) algorithm that can estimate relative pose from two consecutive frames despite of Rolling Shutter (RS) artifacts. In particular, we show that under constant velocity assumption, the errors induced by the rolling shutter effect can be easily rectified by a linear scaling operation on each optical flow. We further propose a 9-point algorithm to recover the relative pose of a rolling shutter camera that undergoes constant…

Image Stitching and Rectification for Hand-Held Cameras
TLDR
A new differential homography that can account for the scanline-varying camera poses in Rolling Shutter (RS) cameras is derived, and its application to carry out RS-aware image stitching and rectification at one stroke is demonstrated.
Rolling Shutter Pose and Ego-Motion Estimation Using Shape-from-Template
TLDR

This paper first makes a theoretical contribution by showing that RS two-view geometry is degenerate in the case of pure translational camera motion, and proposes a Convolutional Neural Network (CNN)-based method which learns the underlying geometry from just a single RS image and performs RS image correction.
Learning Rolling Shutter Correction from Real Data without Camera Motion Assumption
TLDR
A deep neural network is proposed to predict depth and camera poses for single-frame rolling shutter correction and it is enabled by training on real images captured by rolling shutter cameras instead of synthetic ones generated with certain motion assumption.
Context-Aware Video Reconstruction for Rolling Shutter Cameras
TLDR
An approximated bilateral motion model is derived, which can serve as an alternative to provide a simple but effective GS frame initialization for related tasks and achieves superior performance over state-of-the-art methods in terms of objective metrics and subjective visual quality.
