FourierConjgImg

DESCRIPTION

Computes the conjugate of a frequency domain image and divides by a constant scaling factor. The input image is expected to be in the packed format produced by the ForwardFFTImg module (see format description in ForwardFFTImg documentation). The Fourier transformation is discussed in:

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