Low Memory Access Video Stabilization for Low-Cost Camera SoC
Sensors, 2022 Video stabilization is one of the most important features in consumer cameras. Even simple video stabilization algorithms may need to access the frames several times to generate a stabilized output image, which places a significant burden on the camera ...

Modelization and Characterization of a CMOS Camera as an Optical Real-Time Oscilloscope
IEEE Photonics Journal, 2020 Complementary Metal-Oxide Semiconductor (CMOS) camera sensors are embedded in many consumer electronics products: thanks to the Rolling Shutter (RS) readout mode, they can detect a time-varying light intensity, which is the key to realize Optical Camera ...

Solid-fluid transition in a granular shear flow [PDF]
, 2004 The rheology of a granular shear flow is studied in a quasi-2d rotating cylinder. Measurements are carried out near the midpoint along the length of the surface flowing layer where the flow is steady and non-accelerating. Streakline photography and image

Rolling Shutter Camera Relative Pose: Generalized Epipolar Geometry [PDF]
2016 IEEE Conference on Computer Vision and Pattern Recognition (CVPR), 2016 The vast majority of modern consumer-grade cameras employ a rolling shutter mechanism. In dynamic geometric computer vision applications such as visual SLAM, the so-called rolling shutter effect therefore needs to be properly taken into account. A dedicated relative pose solver appears to be the first problem to solve, as it is of eminent importance to

Time calibration of thermal rolling shutter infrared cameras [PDF]
Infrared Physics & Technology, 2017 Abstract The working principle of nearly all uncooled microbolometer thermal imaging systems is based on the rolling shutter principle. This results in time delays between rows giving rise to distorted and blurred images which are difficult to correlate with, for example instantaneous numerical simulation results for nondestructive evaluation.

Visible Light Communication Using Receivers of Camera Image Sensor and Solar Cell
IEEE Photonics Journal, 2016 We propose an electronic label and sensor system using visible light communication (VLC). The downlink signal is transmitted by a white-light light-emitting diode (LED) lamp that can provide lighting, VLC, and energy harvesting for mobile devices.

Minimal Solvers for Monocular Rolling Shutter Compensation under Ackermann Motion
, 2017 Modern automotive vehicles are often equipped with a budget commercial rolling shutter camera. These devices often produce distorted images due to the inter-row delay of the camera while capturing the image.
