Online Non-Negative Multi-Modality Feature Template Learning for RGB-Assisted Infrared Tracking

IEEE Access, 2019
Infrared sensors have been deployed in many video surveillance systems because of the insensibility of their imaging procedure to some extreme conditions (e.g. low illumination condition, dim environment).

RESEARCH OF IMAGES FILTRATION METHODS IN COMPUTER SYSTEMS

Сучасні інформаційні системи, 2021
It is known that human eyes are less sensitive to color, than to their brightness. In the RGB color space, all three components are considered equally important, and they are usually stored with the same resolution. However, you can display a color image

Evaluating RGB channels in remote photoplethysmography: a comparative study with contact-based PPG

Frontiers in Physiology, 2023
Remote photoplethysmography (rPPG) provides a non-contact method for measuring blood volume changes. In this study, we compared rPPG signals obtained from video cameras with traditional contact-based photoplethysmography (cPPG) to assess the ...

Photothermal Heat Spreading for Uniform Pixel Activation in NIR Laser‐Driven Thermochromic Liquid Crystal Displays

Advanced Materials Interfaces, EarlyView.
A pixelated full‐color display is driven by a 1064 nm near‐infrared laser without electrical wiring. A graphite photothermal layer converts light into heat, while an aluminum heat‐spreading layer redistributes it for uniform color within each pixel. Optimizing pixel size and spacing suppresses thermal crosstalk, enabling non‐contact reproduction of ...
