DESCRIPTIONMultiplies two complex frequency domain images, effectively producing the frequency domain representation of their time domain convolution. The inputs must have equal sizes and must be frequency domain images in the packed format produced by the ForwardFFTImg module (see format description in ForwardFFTImg documentation). The Fourier transformation and the cross correlation are discussed in:
