This ForwardFFTFromImage Method performs a forward Fast Fourier Transform of the input image. The difference between this function and ForwardFFT is that this function takes an ImGearPage Class as the input object.
 |
You must keep track how the transform is centered, as well as the scaling method, in the forward FFT in order to know how to de-center it during the inverse FFT. |
This method can be applied only to 8, 16, or 32bit grayscale images with one channel.
Method ImGearFrequencyProcessingVerifier.CanApplyForwardFFTFromImage Method can be called to check whether the operation can be performed or not.
