The function implement the 1D Walash Transform which can be used in signal processing,pattern recognition and Genetic algorithms. The Formula of 1D Walsh Transform is defined as :
1 | | b[i](m)*b[q-1-i](u)
W(u) = --- / f(m)| | (-1) ,u = 0,...,N-1
N ---- | |
where for instance ,A[i] is the ith indices of A
The function implement the 1D Walash Transform which can be used in signal processing,pattern recognition and Genetic algorithms. The Formula of 1D Walsh Transform is defined in mfile
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.
The script allows to easily fit predefined complex analytical laws exploiting the potentiality of Genetic Algorithms.
The script receives as input the handle to the analytic laws to be fitted to data. Such law may depend on multiple variables...
The script is a good demo technique to show how complex numeric data can be exported and imported in MATLAB
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])
Polygamma function of arbitrary order valid in the entire complex plane. This is a generalization of the Psi (or digamma) function. Useful for summing infinite series.
Wavelet based square image enlargemant (zooming in).
Zooming is performed by employing the idwt2() MATLAB function, with a wavelet
family determined by 'wname'.
The size and quality of the final zoomed image 'output_image' depends on
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...

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.
Kruskal's algorithm is used to find the branches of a ''tree'' having the minimum weight in a system of branches. The application of this algorithm is wide. One example is in finding the shortest (and cheapest) path of interconnecting several...
