ChromaFlash: Snapshot Hyperspectral Imaging Using Rolling Shutter Cameras

Proceedings of the ACM on Interactive, Mobile, Wearable and Ubiquitous Technologies
Hyperspectral imaging captures scene information across narrow, contiguous bands of the electromagnetic spectrum. Despite its proven utility in industrial and biomedical applications, its ubiquity has been limited by bulky form factors, slow capture times, and prohibitive costs.

Rolling shutter and motion blur removal for depth cameras

2016 IEEE International Conference on Robotics and Automation (ICRA), 2016
Structured light range sensors (SLRS) like the Microsoft Kinect have electronic rolling shutters (ERS). The output of such a sensor while in motion is subject to significant motion blur (MB) and rolling shutter (RS) distortion. Most robotic literature still does not explicitly model this distortion, resulting in inaccurate camera motion estimation.

Accurate 3D Reconstruction from Small Motion Clip for Rolling Shutter Cameras

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2019
Structure from small motion has become an important topic in 3D computer vision as a method for estimating depth, since capturing the input is so user-friendly. However, major limitations exist with respect to the form of depth uncertainty, due to the narrow baseline and the rolling shutter effect.

Automatic video deshearing for skew sequences capturedby rolling shutter cameras

2011 18th IEEE International Conference on Image Processing, 2011
A novel automatic video deshearing is proposed to reduce the skew artifacts (jelly artifacts) in sequences captured by CMOS censor cameras. The paper first considers the principles of skew artifacts in rolling shutter cameras. Then a deshearing algorithm with high accuracy is discussed with automatic skew artifact detection.

Experimental Demonstration of Dual Camera Receivers in M-PAM Rolling Shutter Based Visible Light Communication

International Symposium on Circuits and Systems
This study demonstrates the communication performance of rolling shutter based visible light communication (RS-VLC) using dual camera receivers. In RS-VLC, the modulated signals emitted from the light source are captured as stripes based on the exposure ...
