gaussn 高斯高通滤波器的截止（标准偏差） D0 。
如果提供，正被忽略。 M和N应该是偶数的密度泛函过滤。-THIS IS NOT A STANDARD MATLAB FUNCTION
H = hpfilter (type,M,N,D0,n) creates the transfer function of a highpass filter, H, of the specified type and size MxN. Possible values for type, D0, and n are: ideal Ideal highpass filter with cutoff frequency D0. Ifsupplied, n is ignored. btw Butterworth highpass filter
of order n, and cutoff D0.

Description: * Frequency domain filtering
-1. Discrete Fourier Transform
Write a C++ function for each of following:
(a) Multiply the input image by (-1)x+y to center the transform for filtering.
(b) Compute the two-dimensional discrete Fourier transform.
(c) Compute the inverse two-dimensional discrete Fourier transform.
(d) Multiply the result by (-1)x+y and take the real part.
(e) Compute the Fourier spectrum.
2. Highass Filtering
(a) Write a C++ function for the transfer function of the Gaussian highpass filter in Eq. (4.4-4).
