Abstract
Many kinds of labels are recently printed on goods to show environmental information. However, most of them are difficult to understand intuitively. So in this paper, a camera phone based recognition system is proposed to give environmental information. An image of a label captured with a camera phone is transmitted to a server on which the image is recognized with SIFT. Then, the related information to the label is set back to the camera phone. Experimental results with very popular environmental labels concerning recycle information show effectiveness of the system.
