傅里叶变化(FFT)是光学数值模拟(特别是光学传播中)的重要工具。 在matlab中实现FFT是依靠fft函数。那么我们在实现FFT时,一定要知道matlab中的fft做了什么,以及与理论上傅里叶变换的对应关系。 在matlab Documentation中,可以看到 Y= fft(X)computes thediscrete Fourier transform(DFT) ofXusing a fast Fourier tran...

I'm wondering why the dft function in OpenCVC++ is a lot slower than fft2 for 2D matrices. The following C++ code is from the documentation: void fft2(const Mat in, Mat &complexI) { Mat padded; int m = getOptimalDFTSize(in.rows); int n = getOptimalDFTSize(in.cols); copyMakeBor...
