Due to the reliability and high efficiency, the white LED sources are widely used for general illumination, and they can also be applied for data transmission. In this paper, we propose a smart lighting system of visible light FSO transmission with white LEDs as the transmitter and a photo sensor as the receiver. The advantage is that the brightness of LEDs(More)
With the fast development of 3D model construction and widespread popularity of 3D graphic engines, more applications employ 3D geometric models to provide an interactive environment. As the number of 3D models increases, some 3D model retrieval systems have been proposed for indexing and matching these models. An important issue in a retrieval system is(More)
