English Description：
This is my Gaussian high-pass filter Matlab code use for digital image processing. In the case of Gaussian filtering, the frequency coefficients are not cut abruptly, but smoother cut of process is used instead. Thus also take advantage of the fact that the DFT of a Gaussian function is a also a Gaussian function. The Gaussian high pass filters attenuates frequency components that are near to image center. The Gaussian high pass is given by: Hu,v=1-
