摘要： 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.

摘要： One embodiment of the present invention provides a system that removes noise from an image. During operation, the system first identifies blobs in the image, wherein a blob is a set of contiguous pixels which possibly represents a character or a portion of a character in the image. Next, the system analyzes the blobs to dynamically determine a “noise threshold” for the blobs. The system then removes blobs from the image which are below the noise threshold.

摘要： A system creates an electronic version of a document from page-images of the document, wherein the electronic version replicates both the logical content and the physical appearance of the original document. During operation, the system receives the page-images for the document. Next, the system extracts character images from the page-images, and generates a synthetic font for the document from the extracted character images. Finally, the system constructs the electronic version of the document by, using the synthetic font to represent text regions of the document, and by using image-segments extracted from the pages-images to represent non-text regions of the document.

摘要： A system for producing a raster image derived from coded and non-coded portions of a hybrid data structure from an input bitmap including (1) a data processing apparatus, (2) a recognizer which performs recognition on an input bitmap to the data processing apparatus to detect identifiable objects within the input bitmap, (3) a mechanism for producing a hybrid data structure including coded data corresponding to the identifiable objects and non-coded data derived from portions of the input bitmap which do not correspond to the identifiable objects, and (4) an output device capable of developing a visually perceptible raster image derived from the hybrid data structure. The raster image includes raster images of the identifiable objects and raster images derived from portions of the input bitmap that do not correspond to the identifiable objects. The invention includes a method for producing a hybrid data structure for a bitmap of an image having the steps of: (1) inputting a signal comprising a bitmap into a digital processing apparatus, (2) partitioning the bitmap into a hierarchy of lexical units, (3) 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 (4) storing each lexical unit in a hybrid data structure as either an identifiable object or a non-identifiable object.
