Image can be compressed using KL transform the code demonstrates the method
Lee filter for reducing speckle noise in images. Vectorised version of http://www.mathworks.com/matlabcentral/fil...9456-lee-filter
Implementation of Progressive Switching Median Filter
This program can be used to generate sobel filter of any size.
A phone-like DTMF tool with GUI using several methods, FFT,goertzel and filter banks.
Just run the gui.
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])
This is a demo program of color filter array (CFA) image color reproduction. J. Tian, W. Yu and L. Ma, "Color filter array color reproduction using cycle-spinning," International Journal of Electronics and Communications, Vol. 64, No. 6,...
A kalman filter based on a constant velocity model and constant process noise reaches is steady-state after few samples. In steady-state the actual position estimate of the kalman gives the same performances of a zero+two-pole lowpass filter...
Adds an additional dropdown menu to the page listing(also works for other hierarchal post types that support page templates) to filter by page template.
Upload the page-template-filter folder to the...
ifilter(x,y) or ifilter(y) or ifilter([x y]) or ry=ifilter(x,y,center,width,shape,plotmode,filtermode)
Keyboard-operated interactive Fourier filter function for time-series signal (x,y), with keyboard controls that allow you to adjust the...
2-D zero phase digital FIR filter using Hamming Window
Tracking of a red point in video which is moving according the parametric equation of Astroid using 5 equations of Kalman Filter.
Generate Video file makes a video of a Large square block moving according the equation of Astroid.
Here is the root raised cosine match filter example. The code exploits the persistent memory option of filter for the tails of RRC. Thus, you don't have to apply filter to all data at the same time.
Simple Draw Helix Spring 3D Rotate Translate Transform Dilate Save JPG
The input of the filter is a armonic signal which is sum of two sinusoidal component. The frequency behavior of the filter is chose to attenuate the high spectral component of the input signal with 20 dB.
Simple Zero Phase Distortion Multiplier-less Gaussian Low-Pass & High-Pass Digital Filter of a Linear Chirp.
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)...
