A coded visual marker for video tracking system based on structured image analysis

This paper proposes a new kind of visual marker for a wearable computer based augmented reality (AR) system. Various marker systems have already been developed for using with an AR system. However, the improvement is needed to use these marker systems on a wearable AR system in terms of the amount of information or the width of the recognizable area. The main feature of our visual marker is a large amount of information that it can possess. Our marker consists of 32 bits data area with error detection code. This feature enables a wearable AR system to be used in various ways.
