Abstract: The system and methods of the present invention provide a processing function that is useful for controlling any type of transaction between providers and consumers of information services. The invention provides a transaction framework that dynamically integrates a plurality of service providers and consumers based on transaction context data. Transactions between services are described using a transaction definition. A transaction definition specifies the details of the transaction using a uniform specification model, where services are classified through a standardized taxonomic structure. The processing function analyzes service classification during a transaction to determine the appropriate configuration and processing strategy.

Abstract: A discrete transform image data compression system in which frequency transform coefficients are modified in accordance with a matrix of quantizer values employs a predefined plurality of quantization matrices to adaptively select, on a document-by-document basis, an approximate memory packet size for each document's compressed image data storage by selecting one of the plurality of quantization matrices in accordance with the packet size estimate obtained for each document image. Additionally, the system employs generation of contrast reduction and gray level stretch remapping curves as a function of global image data characteristics, such as a gray level histogram of the document image data. The remapping curves are utilized to preprocess the image data for more effective data compression.
