SnapToTell: a Singapore image test bed for ubiquitous information access from camera

With the proliferation of camera phones, many novel applications and services are emerging. In this paper, we present the SnapToTell system, which provides information directory service to tourists, based on pictures taken by the camera phones and location information. We present also experimental results on scene recognition based on a realistic data set of scenes and locations in Singapore which form a new original application oriented image test bed freely available.
