Abstract

An example page taken from each document in a document database is processed by a page processor to yield an iconic representation for the example page. To form the iconic representation, the example page is segmented into text regions, line art regions, photograph regions, etc., and each region is reduced in a manner appropriate for that image type. Text is replaced with a block font and reduced, while graphics are reduced in level and/or spatial resolution. The reduced regions of the example page are then reassembled into the icon. When multiple icons are printed on a guide page, a user can visually identify the icon for an example page of a target document and supply the icon, or a label for the icon, to a document retrieval system, which selects candidate matching documents from the document database. For simplified processing, characters can be blocked and words formed into solid line segments with lengths proportional to word lengths.

Claims

1. A method of routing a document electronically, comprising the steps of:

generating a plurality of destination icons to form a guide page, wherein a destination icon is a representation of a specific destination;

selecting at least one destination icon from said guide page;

marking said selected destination icon;

extracting at least one feature of said selected destination icon;

using said extracted feature to electronically identify at least one electronic address of said specific destination correspondinf to said extracted freature; and

electonically routing said document to said electronic address.

2. The method of claim 1, wherein said specific destinations correspond to specific people.

3. The method of claim 1, wherein said specific destinations correspond to specific groups of people.

4. The method of claim 1, wherein said destination icons are comprised of destination symbols.

5. The method of claim 1, wherein said destination icons are comprised of pictures and names.

6. The method of claim 1, further comprising the step of entering said selected destination icon into a document server system prior to said extraction step.

7. The method of claim 6, wherein said entering step further comprises the step of scanning, said selected destination icon.
