Alfréd Haar — (October 11, 1885 March 16, 1933) was a Hungarian mathematician. The Haar measure, Haar wavelet, and Haar transform are named in his honor. Together with Frigyes Riesz, he made the University of Szeged a centre of mathematics.PublicationHaar A.… … Wikipedia
Stationary wavelet transform — Haar Stationary Wavelet Transform of Lena The Stationary wavelet transform (SWT)[1] is a wavelet transform algorithm designed to overcome the lack of translation invariance of the discrete wavelet transform (DWT). Translation invariance is… … Wikipedia
Discrete wavelet transform — An example of the 2D discrete wavelet transform that is used in JPEG2000. The original image is high pass filtered, yielding the three large images, each describing local changes in brightness (details) in the original image. It is then low pass… … Wikipedia
Mellin transform — In mathematics, the Mellin transform is an integral transform that may be regarded as the multiplicative version of the two sided Laplace transform. This integral transform is closely connected to the theory of Dirichlet series, and is often used … Wikipedia
