Abstract
Video recordings of meetings and scanned paper documents are natural digital documents that come out of a meeting. These can be placed on the Internet for easy access, with links generated between them by matching scanned documents to a segment of the video referencing the scanned document. Furthermore, annotations made on the paper documents during the meeting can be extracted and used as indexes to the video. An orthonormal transform, such as a Digital Cosine Transform (DCT) is used to compare scanned documents to video frames.
