The paper proposes a novel camera-based receiver for visible light communications for a short range mobile-to-mobile communications link. The receiver captures data from the screen of a transmitting smartphone and uses the speeded up robust features algorithm to effectively detect it. The receiver performs a projective transformation to accurately eliminate perspective distortions caused by the displacement...
In this paper we present the experimental work on object detection in the Smartphone visible light communications (SVLC) system. In SVLC, the Smartphone emits encoded images using its panel light under different conditions (link range and angles) and the transmitted data is captured by a receiving phone. The captured image is processed using the Speeded Up Robust Features (SURF) technique, which enables...
