任何人都可以向我解释一下，Laplace-Hamming过滤器是什么？ 这是我试过的，我是正确的
f = imread('cameraman.tif');
h = fspecial('laplacian'); % Laplacian filter
f2 = imfilter(f,h);
h2 = hamming(256)*hamming(256)'; % Hamming filter
filtered = ifft2(fft2(double(f2)).*fftshift(h2)); % apply hamming filter to laplacian
imshow(abs(filtered));
