Evaluating derivatives: principles and techniques of algorithmic differentiation
Griewank A., Walther A., Society for Industrial and Applied Mathematics, Philadelphia, PA, 2008. 460 pp. Type: Book
Evaluating derivatives of functions is a problem frequently encountered in various areas of scientific computing. This is especially important if the task at hand comes from a nonlinear problem, regardless of whether the precise background is in...

Progressive lossy to lossless compression of ROI in mammograms: effects on microcalcification detection
Zyout I., Abdel-Qader I., Al-Otum H. Integrated Computer-Aided Engineering 15(3): 241-251, 2008. Type: Article
Compression of medical images should not degrade the quality of the regions that are critical for diagnosis of diseases. Zyout et al. present one such application for mammograms, including its effect on microcalcification detection. The scheme...

An accurate nonuniform fourier transform for SPRITE magnetic resonance imaging data
Rioux J., Halse M., Aubanel E., Balcom B., Kaffanke J., Romanzetti S., Dierkes T., Shah N. ACM Transactions on Mathematical Software 33(3): 16-es, 2007. Type: Article
Magnetic resonance imaging (MRI) is a powerful technique for medical imaging. The MRI signal is generated by excitation of a sample, such as living tissue, with a radio frequency pulse at an appropriate frequency. The frequency spectrum is...

Time delay estimation using fractional Fourier transform
Sharma K., Joshi S. Signal Processing 87(5): 853-865, 2007. Type: Article
The fractional Fourier transform is a generalization of the classical Fourier transform that has an extra parameter that gives some additional flexibility. This paper demonstrates how this additional flexibility can be used in a very efficient...

Fast computation of RBF coefficients using FFT
Abe Y., Iiguni Y. Signal Processing 86(11): 3264-3274, 2006. Type: Article
Radial basis functions (RBFs) are real valued functions whose domain is in a real or complex vector space. The term “radial” refers to the fact that their value at a point depends only on the distance of that point from a fixed...
