据我所知,生成高斯低通滤波器的公式是:
[x y] = meshgrid(round(-N/2):round(N/2), round(-N/2):round(N/2));
GaussianFilter = exp((-x.^2/(2*sigma^2)-y.^2/(2*sigma^2)));
在这种情况下,高通滤波器的公式应该是什么?
答案 0 :(得分:2)
我写的答案基于此 - MATLAB Image Sharpening - Gaussian High Pass Filter using (1- Gaussian Low Pass Filter)和评论。
GaussianFilterHigh = 1 - exp((-x.^2/(2*sigma^2)-y.^2/(2*sigma^2)));
