I have a blurred and noisy image $X$, I want to apply the Wiener filter on it and get a deblurred and denoised image $Y$ (i.e apply inverse of blurring filter while at the same time reducing some noise, if not accentuating it). I'd like to measure the SNR in both in order to evaluate the quantity of noise deleted.

STFT can be successfully used on sound data (with a .wav soundfile for example) in order to do some frequency-domain modifications (example : noise removal).
With N=441000 (i.e. 10 seconds at sampling rate fs=44100), windowsize=4096, overlap=4, STFT produces approximatively a 430x4096 array (first coordinate : time fra... |

We used to classify signals as 1D and 2D etc ie one dimensional and two dimensional. For example a periodic square wave signal is 1D and an image is a 2D signal etc (reference - Signals and systems by Simon Haykin and Barry Van Veen, 2nd edition , page 2).
But the same periodic square wave signal can be decomposed usin... |

I recently was studying gabor filters and came to know that they have a shortcoming that they do have a minimum but some reasonable dc component.

If there are any other limitation of gabor filters then please do tell me.
thanks..

I have read in many papers that time complexity of WPT is $O(N \log(N))$, but I would like to know what is the effect of Levels in the time complexity.
Must it be one of the following ?
$O(2^{L} ~N~ \log(N))$
$O(2^{L+1} ~N~ \log(N))$
$O(L ~N ~\log(N))$
$ L$ is the number of decomposition levels

When we are do a discrete Gabor transform on a 1D signal, we apply a Gaussian window on a segment of the signal.
