We have developed omnidirectional-view 3D displays using multiple mini-projectors. Three types of synchronization structure are developed to ensure the accurate synchronization between the projectors and the rotating screen. Therefore, low-cost and low-speed display devices can be used to realize natural-looking three-dimensional (3D) scene with full color and high resolution.
This paper introduces a novel augmented reality shooting game named “Soul Hunter”, which has been successfully operating in a theme park in China. Soul Hunter adopts an innovative infrared marker scheme to build a mobile augmented reality application in a wide area. It is an extension of the traditional first person game, in which a player is able to fight with virtual ghost through a gunlike device...

Background modeling is one of the key techniques in video surveillance system. When the training images contain more moving objects or its number is not sufficient, the existing methods normally end up with incorrect background estimates. In this paper, we study a type of method on data analysis, i.e., Robust Principle Component Analysis (RPCA), and present its application on the background modeling...
In this paper, we propose a real-time and adaptive method for labeling and recognition of multiple infrared markers. A single-frame based iteration process is developed to obtain the suitable threshold. A sliding window is proposed to propagate the preliminary labels and to reduce the capacity of equivalent tables handling. The labeling and recognition are realized by merging the results of domains...
Mobile phones with a camera function are capable of capturing image and processing tasks. Quick response code has been widely used in industrial information tagging applications where high data capacity, robust error corrections are required. It has become a kind of mobile 2D barcode which is used widely in China and Japan. In deal with the influence by the different light conditions and noise, a...
The bar code images captured by camera phone have natural disadvantages in the complex environment, such as blur, low contrast, high brightness, etc. Therefore, it is difficult to decode the bar code successfully without preprocessing. Binarization plays an important role in image preprocessing. In this paper, we regarded time complexity and adaptability under the complex environment as a standard...
