Image Filtering
no vote
Image filtering using matlab code.
In this file we have a conversion of image to frequency domain(using discrete fourier transform(function created for me using matrix way)) then before a convolution with filter in frequency domain, low, high and band pass and finally with this product we make a fourier transform inverse.

Short-time Fourier transform
no vote
The short-time Fourier transform ( STFT ) is used for transforming a signal of time to frequency domain, but often is used when our signal has low amplitude and some ranges of frequency close.
