A document management system includes one or more document repositories for storing documents and a document notification and delivery service (DNDS) for detecting documents pertaining to subjects that are stored in the document repositories. A plurality of workflow modules subscribe to the DNDS to receive documents identified that pertain to subscribed subjects. At least two workflow modules produce documents that are published to the document repositories. Further, a first workflow module publishes to one of the document repositories a first document which is detected by the DNDS and which pertains to at least one subscribed subject of a second workflow module. Subsequent to the publication of the first document by the DNDS to the one of the document repositories, the DNDS delivers the first document to the second workflow module that operates independent from the first workflow module to produce a second document.

Integrating a document management system with a workflow system and method

A method and system for contrast enhancement of an input image that utilizes luminance values of pixels of the input image to derive transforms. The method down-samples and partitions an image into sub-images whereby transforms are generated for selected sub-images. The selected sub-image transforms are used to generate an output transform which is applied to the input image for local contrast enhancement of the image. Furthermore, a decision method as to whether or not the input image is to receive local contrast enhancement wherein darkness features of the input image are compared to threshold values and combined into an expression which results in the determination.

Contrast enhancement of images

A document recommendation system incorporating a document change monitoring agent. For a document recommendation system to be effective, it is desirable to enable users to be cognizant of changes that may occur to the document. The present invention addresses this issue by coupling a document change monitoring agent, which automatically detects changes in referenced documents, with a recommender system, which helps users share and evaluate information in a collaborative way. One advantage of the invention is that it brings human judgement into the relevance evaluation of the detected changes and allows the results to be shared with other people likely to be interested, in such a way that redundant work is decreased. Another advantage of the invention is that it enables Systems Administrators of a document recommendation system to be more efficient in the management of the system.
