Abstract:
A system for producing from an input bitmap of a document a searchable raster image of the document using a hybrid data structure including coded and non-coded portions, the system comprising:a data processing apparatus for receiving an input bitmap representing detected objects in a document; means for performing recognition on the input bitmap to detect identifiable objects searchable as text within the input bitmap; means for creating a searchable hybrid data structure including coded portions corresponding to the identifiable objects and non-coded portions derived from portions of the input bitmap which correspond to non-identifiable objects; an output device for developing a visually perceptible raster image from the hybrid data structure whose appearance is virtually identical to the document and; means for searching the hybrid data structure according to user-specified search criteria, wherein the search criteria is applied to the identifiable objects and the non-identifiable objects of the input bitmap.
