Converting image to a gateway to an information portal for digital signage

Digital signage has recently emerged as a new channel for communicating with people in diverse domains such as advertising, shopping mall and public service. In this paper, we propose a novel data fusion method for converting an advertisement image into a gateway to an information portal based on steganography technology for digital signage. We make the information portal very flexible just by changing the link or by organizing the contents dynamically. Typical contents include product information and summary of user evaluation. To implement this scheme, we first register products of interest with their representative features and quick response (QR) code. The representative points are used for detecting products in images and their QR code is embedded into the detected product area using our steganography technique. We implement a prototype system based on our scheme, and show its effectiveness through extensive experiments.
