【 摘 要 】

Augmented reality applications are increasingly used to enhance physical objects with digital information. In this paper, we present a TouchPaper system that consists of a mobile application and a cloud-based image recognition service. Through an authoring system, images can be linked to online content that will be invoked when a printed version of the image is captured and "touched" on a mobile phone screen. We describe a sBIP (Structured Binary Intensity Pattern) algorithm that performs the matching of the images and evaluate the performance of the overall TouchPaper system.
