Reducing Grayscale Value Fluctuation for Mobile-Phone Camera Based VLC System
Reducing Grayscale Value Fluctuation for Mobile-Phone Camera Based VLC System is a scholarly work, published in 2018 in ''IEEE Photonics Journal''. The main subjects of the publication include greyscale image, bit error rate, reservoir computing, camera phone, artificial intelligence, noise, Visible light communication, electronic engineering, computer vision, computer science, frame rate, mobile phone, CMOS, pixel, rolling shutter, and algorithm. In this paper, for the first time, authors propose an exponent transform (ET) algorithm to decrease grayscale value fluctuation, thus improving the VLC system performance.
