In this paper the time-slot coding scheme is experimentally demonstrated using imaging receiver to provide multiple access for indoor optical wireless communications. The system capacity of 8 Gb/s is achieved for up to 12 users.
The image registration is one of the key steps to achieve three-dimensional (3D) localization and the other image fusion processes. This article presents a registration method based on the combination of edge feature and corner feature. The processing steps include image segmentation, corner detection, edge detection, extraction of interested region, and correspondence points matching. The algorithm...
High-speed wireless connectivity in personal areas is highly demanded and the optical wireless technology is a promising solution. In this paper, recent progress of high-speed optical wireless communication systems in personal area networks is briefly reviewed.
Optical wireless technology has been considered as a promising candidate to provide high-speed wireless connectivity in personal work/living spaces. Previously we proposed and demonstrated a high-speed indoor communication system by incorporating limited mobility with localization function. Furthermore, we showed that by using a novel single channel imaging receiver, better system performance can...
In this paper we experimentally demonstrate an indoor optical wireless based localization system with single channel imaging receiver for personal area network applications. The results show that an accuracy of ∼3.81cm can be achieved.
Direct volume-rendering (DVR) is usually used in medical volume visualization, DVR images tend to be over-loaded with the content (blurred images). Thus, in many practical applications simpler techniques which do not rely on complex transfer functions are employed. For example, maximum intensity projection (MIP) which depicts the maximum value along each viewing ray. In this paper, we improve the...
