Cepstrum-based interferometric microscopy with rolling-shutter cameras

Optics Letters
Cepstrum-based interferometric microscopy (CIM) has risen as a groundbreaking digital holographic microscopy (DHM) technique that overcomes the conventional need of a clean/known reference beam for holographic recording. In CIM, two arbitrary complex object fields interfere each other to provide quantitative phase imaging (QPI) of both at once ...

Multiple View 3D Reconstruction with Rolling Shutter Cameras

2016
Nowadays Rolling shutter CMOS cameras are embedded on a lot of devices. This type of cameras does not have its retina exposed simultaneously but line by line. The resulting distortions affect structure from motion methods developed for global shutter, like CCD cameras.

Exploiting camera rolling shutter to detect high frequency signals

Applications of Digital Image Processing XLII, 2019
Rolling shutter-based image sensors generate images by sequentially illuminating individual pixel rows. While this often results in unwanted image distortion for scenes with motion, we propose methods to exploit the temporal behavior of the rolling shutter to detect periodic changes.

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.

High-speed asynchronous Optical Camera Communication using LED and rolling shutter camera

2015 Seventh International Conference on Ubiquitous and Future Networks, 2015
This paper introduces the asynchronous Optical Camera Communication (asynchronous OCC) using LED and rolling shutter camera as a pair of wireless communication. Aiming to enhance the capacity of unidirectional wireless link, the response of camera is measured, and then the operating frequency range, system architecture, decoding procedure and algorithm

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.

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.

Simulation of rolling shutter acquisition in optical camera communications

2020
The rolling shutter (RS) acquisition mechanism performed by the majority of the digital cameras included in portable devices has been exploited to make receivers for visible light communications (VLC). They are able to decode signals of frequencies higher than the frame rate of the camera, which is a limitation when using global shutter sensors.
