We can observe that when the dimension of A is a multiple of 2, pixel information is misplaced (top-left-corner) or lost (bottom-right-corner)
1st-row L-to-R: Shows an original image GREEN, then its MATLAB's radon transform (a.k.a. sinogram), then its MATLAB's inverse radon transform REED (aka iradon), then the position comparison between the original and reconstructed, NON-MATCHING pixel position: SEPARATE...
The function plot_hht is a realization of the Hilbert-Huang transform (HHT). The HHT decomposes a signal into intrinsic mode functions (or IMFs), and obtain the instantaneous frequency data. It is designed to work well for data that are...
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...

computes the naturally-ordered discrete Hadamard transform
Image can be compressed using KL transform the code demonstrates the method
six different DCT (Discrete Cosine Transform based image fusion techniques are presented
Image fusion using DCT based demo programme is presented.
This function will take two transformation matrices and transform from tr1 to tr2 converting all the points from frame 1-->2
Use: pointsOut = fcn_transformPoints(trOrigin[4x4],trDestination[4x4], pointsToBeMoved[mx3])

Here is another fast implementation of the FGT transform.
The Fourier transform takes a signal in the time domain and maps it, without loss of information, into the frequency domain. The frequency domain representation is exactly the same signal, in a different form. The inverse Fourier transform(IDFT)...

Function for calculaing period of a wave signals in pixels using Hilbert transform.
Single or multiple profiles can be used as input for calculating distribution of periods.
PHP transForm is a form generator and processor that allows a website developer an easy way to view/add/edit/delete data in various databases.
In order to use PHP transForm, you must be using at least PHP4.1.1.
