six different DCT (Discrete Cosine Transform based image fusion techniques are presentedImage fusion using DCT based demo programme is presented. Platforms: Matlab

This demonstration is intended for people who know something about the theory of the discrete Fourier transform, and who would find it helpful to see some its properties demonstrated graphically, using a programming language.The demonstration shows the form of the Fourier components of a signal...

It first transforms to patient coordinates and then to the second coordinates. Both dicom image sets should have the same localizer while scanning.It takes two inputs: dicominfo structures (taken by dicominfo mmand) of two image sets. The outputs are 4x4 transform matrix and 3x3 rotation... Platforms: Matlab

The Alpert transform is a multiwavelets transform based on orthogonal polynomials. It was originally designed for the resolution of partial differential and integral equations, since it avoids boundary artifact and can be used with an arbitrary sampling.The reference for the numerical...

UM Video Color Filter is a powerful transform filter that allows invert and grayscale the video, change the brightness, contrast, hue and saturation. UM Video Color Filter can be used during capture for real-time processing, during conversion or during playback to enhance existing media files. Platforms: Windows

PCSA is a frequency domain analysis technique that can be used to transform PSDs (as those in a spectrogram) to the form of a two-dimensional histogram with frequency-magnitude bins. PCSA can be used to examine the spectral characteristics of a long period of data. It summarizes magnitudes and... Platforms: Matlab

The function implement the 2D dyadic(Paley) ordered fast in-place Walsh-Hadamard transform, which can be used in signal processing, pattern recognition and Genetic alogorithms. This algorithm uses a Cooley-Tukey type signal flow graph and is implemented in N log2 Nadditions and subtractions. Data... Platforms: Matlab

Transform SWF is an easy to use library for reading and writing Flash and Flash Video files. As of 25/11/2010 the latest version (3.0) can now be found at GitHub, https://github.com/StuartMacKay/transform-swf. Platforms: Windows, Mac, Linux

Noisy environments make difficult the pattern recognition tasks. In this sense, and due to the artifacts that are present in the acquisition process, the most of the biomedical images (i.e. coming from magnetic resonance tests) become noisy and it is complicated even to define a Region Of...
