Abstract

Automatic CD cover recognition has interesting applications for comparison shopping and music sampling. We demonstrate a real-time CD cover recognition using a cameraphone. By snapping a picture of a CD cover with her cameraphone, a user can conveniently retrieve information related to the CD. Robust image feature extraction is applied to overcome the image distortions in the query photo. To limit the amount of data transmitted over a wireless network, we compress the query image or features extracted from the query image. On the database side, fast and reliable image matching against a database of 10,000 CD covers is accomplished using a scalable vocabulary tree.
