A Spline-Based Trajectory Representation for Sensor Fusion and Rolling Shutter Cameras
International Journal of Computer Vision, 2015The use of multiple sensors for ego-motion estimation is an approach often used to provide more accurate and robust results. However, when representing ego-motion as a discrete series of poses, fusing information of unsynchronized sensors is not straightforward.

Cepstrum-based interferometric microscopy with rolling-shutter cameras
Optics LettersCepstrum-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 ...

High Quality Structure from Small Motion for Rolling Shutter Cameras
2015 IEEE International Conference on Computer Vision (ICCV), 2015We present a practical 3D reconstruction method to obtain a high-quality dense depth map from narrow-baseline image sequences captured by commercial digital cameras, such as DSLRs or mobile phones. Depth estimation from small motion has gained interest as a means of various photographic editing, but important limitations present themselves in the form ...

Vibration Extraction Using Rolling Shutter Cameras
2016Measurements of vibrations, such as sound hitting an object or running a motor, are widely used in industry and research. Traditional methods need either direct contact with the object or a laser vibrometer. Although computer vision methods have been applied to solve this problem, high speed cameras are usually preferred.

ChromaFlash: Snapshot Hyperspectral Imaging Using Rolling Shutter Cameras
Proceedings of the ACM on Interactive, Mobile, Wearable and Ubiquitous TechnologiesHyperspectral 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.

Simulation of rolling shutter acquisition in optical camera communications
2020The 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.
