FourierMultImg
DESCRIPTION
Multiplies 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:
Digital Image Processing, Gonzales, R.C., Wintz, P.,
Addison Wesley, Second Edition, 1987, pp 61--137.
