ABSTRACT:
A personal imaging computer system, which is connectable to and operable with a computerized local or wide area network, identifies characters in a document on which the characters are formed. The system scans the document to obtain a gray-scale image of the document, generates a binary image from the gray-scale image by comparing the gray-scale image with the threshold, segments the binary image to locate individual characters within the binary image and to determine the shape of the individual characters, extracts gray-scale image information from the gray-scale image for each such individual character based on the location and shape of the character in the binary image, recognition-processes the extracted gray scale image information to determine the identity of the character, and stores the identity of the character. The character identities are stored in a character file in association with the image so as to facilitate image retrieval with a text-based search over many such character files. Preferably, the image is not stored in its scanned-in resolution, but rather is stored at a reduced resolution so as to reduce memory storage requirements.
