    Abstract: Systems and methods are described for creating a video booklet that allows browsing and search of a video library. In one implementation, each video in the video library is divided into segments. Each segment is represented by a thumbnail image. Signatures of the representative thumbnails are extracted and stored in a database. The thumbnail images are then printed into an artistic paper booklet. A user can photograph one of the thumbnails in the paper booklet to automatically play the video segment corresponding to the thumbnail. Active shape modeling is used to identify and restore the photo information to the form of a thumbnail image from which a signature can be extracted for comparison with the database.
