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.
