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.

Claims

1. An information system, comprising:

first processing device; and

,

a persistent storage device, coupled to the processing device, for storing linking software, wherein the linking software creates a link between a scanned document file and a segment of a video file responsive to a comparison of a transformed scanned document and a transformed video frame.

2. The information system of claim 1, further comprising:

a scanner, coupled to the first processing device, for creating the scanned document file from a physical document.

3. The information system of claim 1, further comprising:

a camera, coupled to the first processing device, for creating the video file.

4. The information system of claim 1, further comprising:

a second processing device, coupled to the first processing device, for viewing the segment of the video.

5. An article of manufacture, including a computer readable memory, comprising:

(a) a first software program for obtaining a scanned document;

(b) a second software program for obtaining a video file; and

(c) a third software program for linking the scanned document to a

(d) segment of the video file.

6. The article of manufacture of claim 5, wherein the third software program includes an orthonormal transform.

7. The article of manufacture of claim 5, wherein the third software program includes a scaling software program.

8. The article of manufacture of claim 5, wherein the third software program includes a software program for removing the least significant information.

9. The article of manufacture of claim 5, wherein the third software program includes a software program for removing the margins of the scanned document.

10. The article of manufacture of claim 5, wherein a fourth software program extracts handwritten annotations from the scanned document.

11. The article of manufacture of claim 5, wherein the third software program links the scanned document to multiple segments of the video file.

12. The article of manufacture of claim 5, wherein the third software program compares color information from the scanned document to color information from the video file.
