The problem I have is that I open an Image from a GUI using Qt (through the class I createdImageFrame, this class has defined the PixelType as follows:
What is the fastest FFT implementation in Python? It seems nump开发者_JAVA技巧y.fft and scipy.fftpack both are based on fftpack, and not FFTW. Is fftpack as fast as FFTW? What about using multithread
I am in need of assistance (documentation, sample code, etc.) in how to develop a audio spectrum using JACK and fft开发者_JAVA百科w in C/C++. I am developing on Mac OS X (10.6+). Any help will be much
I\'m currently working with the FFTW2 (Fastest Fourier Transform in the West) library, and after writing a successful routine in Fortran, I am moving on to C.However, I\'m having some trouble with dat
Hi all I am using the fftw C libraries to compute the frequency spectrum for some signal processing applications on embedded systems. However, in my project I have run into a slight hinderence.
I am trying to compute the FFT and then the IFFT just to try out if I can get the same signal back but I am not really sure how to accomplish it.This is how I do the FFT:
I use fftwpp to transform both my data and my convolution kernel into the fourier space, multiply them together like in a scalar prod开发者_JAVA百科uct and convert them back to the real space. When I
I am trying to run FFTW code in a mex file.This is strictly for the purpose of development and testing.After some googling, I see that oth开发者_如何转开发ers have tried to do something similar and ha
I am trying to figure out how to use the batch mode offered in the CUFFT library. I basically have an image that is 5300 pixels wide and 3500 tall. Currently this means I am running 3500 1D FFT\'s on
In the char I have posted below, I am comparing the results from an IFFT run in FFTW and CUFFT. What are the possible reasons this is coming out different? Is it really THAT much round off error?
