Automated system for indexing graphical documents having associated text labels
First Claim
1. An automated indexing system for indexing documents, which include graphics having associated text labels, in a manner allowing object querying within said documents, comprising:
- a microprocessor for;
a) processing graphic portions of a document and identifying isolated graphic objects within said graphic portions;
b) recognizing text labels in said graphic portions;
c) relating said isolated graphic objects to text labels associated therewith; and
a database for storing references to said isolated graphic objects and said text labels associated therewith in a queryable database index of said database, for independent retrieval of said isolated graphic objects and said associated text labels upon directing an independent query thereto.

Abstract
A system for image indexing for the domain of technical manual documents depicting line drawing images of physical equipment. Such line drawings are often associated with text labels that indicate references to component parts in an associated table. The indexing system locates regions containing a machine part in relevant pages of the manual in response to a query describing the part. The query supplied by the user is a textual description of the machine part from which an associated geometric description of the object is retrieved. The indexing mechanism includes two stages, i.e., selection and recognition. The selection phase involves isolating relevant images from the document database using a combination to textual and visual processing and indicating the appropriate regions within those images that are likely to contain the queried machine part. Model-based object recognition then confirms the presence of the part at that location by finding a match of features between the part and the model using a 3D model description associated with the textual query.

2. A method of processing a document containing graphics and text for use in an indexing system associated with a computer implemented database management system, wherein:
-
a bitmapped image containing graphic portions further comprised of isolated graphic objects having associated text labels is received and stored; said bitmapped image is processed to identify said isolated graphic objects and to identify and recognize said text labels therein; said text labels and said isolated graphic objects are associated; references to said isolated graphic objects and said associated text labels are stored in a queryable database index, for retrieval of graphic objects and associated text upon directing a query independently thereto. - View Dependent Claims (3, 4)

5. An automated image indexing system for indexing graphical objects within graphical portions of documents in a manner allowing querying for said objects independently of said graphical portions, comprising:
-
means for processing graphic portions of documents into isolated connected graphical regions; means for approximately localizing queried graphical objects by associating existing annotating text words with said connected graphical regions; and means for automatically isolating single graphical objects from said connected graphics regions. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16)
