ABSTRACT:
A system for producing a raster image derived from a data structure including a data processing apparatus, a recognizer which performs recognition on an input bitmap to the data processing apparatus to detect identifiable objects within the input bitmap, a mechanism for producing a hybrid data structure including coded data corresponding to the identifiable objects and to non-identifiable objects and the input bitmap, and an output device capable of developing a visually perceptible raster image derived from the input bitmap in the hybrid data structure. The raster image is derived from the input bitmap and thus includes no misrecognition errors. It includes a method for producing a hybrid data structure for a bitmap of an image having the steps of inputting a bitmap into a digital processing apparatus, partitioning the bitmap into a hierarchy of lexical units, assigning labels to a label list for each lexical unit of a predetermined hierarchical level, where labels in the label list have an associated confidence level, and storing each lexical unit in a hybrid data structure as either an identifiable object or a non-identifiable object. The entire input bitmap or portions thereof are also stored in the hybrid data structure to be displayed.
