Fast Rolling Shutter Correction in the Wild
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2023 This paper addresses the problem of rolling shutter correction (RSC) in uncalibrated videos. Existing works remove rolling shutter (RS) distortion by explicitly computing the camera motion and depth as intermediate products, followed by motion compensation.

Direct Sparse Odometry with Rolling Shutter [PDF]
, 2018 Neglecting the effects of rolling-shutter cameras for visual odometry (VO) severely degrades accuracy and robustness. In this paper, we propose a novel direct monocular VO method that incorporates a rolling-shutter model. Our approach extends direct sparse odometry which performs direct bundle adjustment of a set of recent keyframe poses and the depths

Deep network for rolling shutter rectification
CoRR, 2021 CMOS sensors employ row-wise acquisition mechanism while imaging a scene, which can result in undesired motion artifacts known as rolling shutter (RS) distortions in the captured image. Existing single image RS rectification methods attempt to account for these distortions by either using algorithms tailored for specific class of scenes which warrants ...

Empirical modelling of rolling shutter effect [PDF]
2014 IEEE International Conference on Robotics and Automation (ICRA), 2014 We propose and evaluate a novel methodology to identify the rolling shutter parameters of a real camera. We also present a model for the geometric distortion introduced when a moving camera with a rolling shutter views a scene. Unlike previous work this model allows for arbitrary camera motion, including accelerations, is exact rather than a ...

Rolling Shutter Correction in Manhattan World [PDF]
2017 IEEE International Conference on Computer Vision (ICCV), 2017 A vast majority of consumer cameras operate the rolling shutter mechanism, which often produces distorted images due to inter-row delay while capturing an image. Recent methods for monocular rolling shutter compensation utilize blur kernel, straightness of line segments, as well as angle and length preservation.
