Filtering with Wavelet Transforms

Raw ECG Signal
Discrete time wavelet transforms have found engineering applications in computer vision, pattern recognition, signal filtering and perhaps most widely in signal and image compression. In 2000 the ISO JPEG committee proposed a new JPEG2000 image compression standard that is based on the wavelet transform using two Daubechies wavelets. This standard made the relatively new image decomposition algo...

Precision and Reproducibility in Computing

Run-to-run reproducibility in computing is often assumed as an obvious truth. However software running on modern computer architectures, among many other processes, particularly when coupled with advanced performance-optimized libraries, is often only guaranteed to produce reproducible results only up to a certain precision; beyond that results can and do vary run-to-run. Reproducibility is inte...

Special Functions

Motivated by the need of some special functions when writing signal processing code for NMath, we decided to add a suite of special functions to be included in NMath 6.1. While the field of special functions is vast [1], our 41 functions cover many of the most commonly needed functions in physics and engineering. This includes the gamma function and related functions, Bessel functions, elliptic i...
