Method and apparatus for synchronizing, displaying and manipulating text and image documents

Abstract: The present invention provides a method and apparatus for extracting, synchronizing, displaying, and manipulating text and image documents in electronic form for display. In the preferred embodiment of the present invention, text and image files for documents, such as for example patent documents, are initially stored on separate magnetic tape media. These data files are extracted from the respective tapes and placed onto a faster medium, such as a hard disk drive. The text and image files are synchronized to produce Equivalent Files using heuristic algorithms to create an approximate equivalence relationship between the text and the image files. The Equivalent Files and image files residing on, for example, a hard disk drive or compact disk (CD), are coupled as a resource to a computer display system. The graphic user interface of the present invention permits the user to display, manipulate, and edit the Equivalent File created using the process of the present invention, and to simultaneously view the image file on the display. Using the graphic user interface of the present invention, a user may create libraries of patent Equivalent Files and image files or documents of another type, as well as open cases to include a plurality of different patents or other documents. The Equivalent File may be selectively viewed on the display in an equivalent window. Simultaneous with the viewing of the Equivalent File within the equivalent window, the user may view any portion of an image file within one or more image windows on the display. A variety of other features and functions are provided by the present invention for the manipulation and display of patent documents and other documents on the user interface.

Reversible Watermarking for Knowledge Digest Embedding and Reliability Control in Medical Images

Abstract: To improve medical image sharing in applications such as e-learning or remote diagnosis aid, we propose to make the image more usable by watermarking it with a digest of its associated knowledge. The aim of such a knowledge digest (KD) is for it to be used for retrieving similar images with either the same findings or differential diagnoses. It summarizes the symbolic descriptions of the image, the symbolic descriptions of the findings semiology, and the similarity rules that contribute to balancing the importance of previous descriptors when comparing images. Instead of modifying the image file format by adding some extra header information, watermarking is used to embed the KD in the pixel gray-level values of the corresponding images. When shared through open networks, watermarking also helps to convey reliability proofs (integrity and authenticity) of an image and its KD. The interest of these new image functionalities is illustrated in the updating of the distributed users' databases within the framework of an e-learning application demonstrator of endoscopic semiology.

Electronic document manager

Abstract: Method and an apparatuses for managing electronic documents on a digital processing system or computer. In one embodiment, a web page is accessed on the Internet at a first location. At least a portion of the web page is then displayed. An image file capturing the displayed visual representation of the web page is generated and stored on the computer at a second location. A thumbnail representation is generated from the displayed visual representation. The first location and the second location are then associated with the thumbnail. Textual information included in the displayed visual representation is preserved and added to a searchable database. Subsequent selection of the thumbnail representation allows one to access either the web page at the first location or access the image file stored at the second location. The image file may be viewed without having to access the electronic document at the first location. Annotations may be added to the stored image file in one embodiment. In another embodiment, data of the stored image file may be copied and included with executable viewing code to generate a self-contained viewing application to view the stored image file.

System and method for visualizing and navigating content in a graphical user interface

Abstract: A system and method for visualizing and navigating document content using a condensed representation of a document to provide both a global overview of the distribution of key search terms as well as their immediate context. The invention supports rapid skimming of documents and document collections and enables efficient information finding, in some cases entirely eliminating the need to scroll within a document as with a conventional browser tool. The invention is of particular utility with personal digital assistants, which generally have small displays and limited storage capacity and communication bandwidth in comparison to personal computers. Documents may include conventional text and image files, web pages, audio files, and video files. The invention may also apply to collections of documents.
