Transmission and Reception of Images via Visible Light

Fusion of Infrared and Visible-Light Images

Transmission of Digital Audio with Visible Light

Communication by visual light or VLC by its acronym in English (Visual Light Communication), uses visible light from fluorescent lamps, or light from light emitting diode (LED) to transmit information. The transmission of information is done by modulating the intensity of the LED light. In the receiver the information is initially recovered through a photo-detector, which is usually connected t...

Visible Light Communication for Wireless Data Transmission

Visible Light Communication (VLC) technology, one of the advanced optical wireless communication technologies, in which light in the visible region (375nm-780nm) is used as a medium for data transmission is more secure and achieves high data rates as compared to conventional wireless technologies like Wi-Fi, Bluetooth, Wi-max etc., which use radio waves for communication. While using wireless i...

Recognition of Banknote Fitness Based on a Fuzzy System Using Visible Light Reflection and Near-infrared Light Transmission Images

Fitness classification is a technique to assess the quality of banknotes in order to determine whether they are usable. Banknote classification techniques are useful in preventing problems that arise from the circulation of substandard banknotes (such as recognition failures, or bill jams in automated teller machines (ATMs) or bank counting machines). By and large, fitness classification contin...

Face Matching Between Near Infrared and Visible Light Images

In many applications, such as E-Passport and driver’s license, the enrollment of face templates is done using visible light (VIS) face images. Such images are normally acquired in controlled environment where the lighting is approximately frontal. However, Authentication is done in variable lighting conditions. Matching of faces in VIS images taken in different lighting conditions is still a bi...
