Publication number: 20130266237Abstract: A wavelet coefficient quantization method using a human visual model in an image compression process is provided, which is particularly suitable for remote sensing image compression. A wavelet-domain visual quantization model is obtained through experiments based on human visual characteristics, so as to reflect the relation between distortion of wavelet coefficient blocks and human visual characteristics. The model includes a luminance component, a masking component and a frequency component, where the luminance component is calculated by low frequency coefficients after the kth level wavelet transform, the masking component is calculated by high frequency coefficients of the second and third levels, and the frequency component is calculated by a statistical method. The method may be used in combination with any mainstream wavelet compression method such as EZW, SPIHT or EBCOT.Type: ApplicationFiled: December 16, 2010Publication date: October 10, 2013Applicant: BEIHANG UNIVERSITYInventors: Bo Li, Hai-Heng Cao, Yi-hong Wen, Hong-xu Jiang

Publication number: 20130018841Abstract: A system, method and computer program product for integrating at least one analytical or modeling driver into an existing business analytic environment. The system comprises a BAMS (Business Analytics and Mathematical Sciences) driver, implemented on the memory device and run by the processor, loads a real database driver and redirects a request from a client application to the real database driver. An extension driver, invoked by the BAMS driver, provides an interface to a data modeling or processing software and converts the interface from a software environment compiled by a programming language to another software environment targeted to another programming language. The extension driver extends or overrides functionalities of the BAMS driver. Implementing the BAMS driver and the extension driver in the existing business analytic environment do not require any change made on the existing business analytic environment.Type: ApplicationFiled: August 29, 2012Publication date: January 17, 2013Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Michael Adendorff, Heng Cao, David L.
