matlab gabor 滤波器

0. gabor 基本原理

1. matlab 内置对 gabor 的支持

• gabor：Create Gabor filter or Gabor filter bank
  • g = gabor(wavelength,orientation)

g = gabor([5, 10], [0, 90]);

figure;
for p = 1:length(g),
    subplot(2, 2, p);
    imshow(g(p).SpatialKernel, []);
    lambda = g(p).Wavelength;
    theta = g(p).Orientation;
    title(sprintf('Re[h(x, y)], \\lambda = %d, \\theta = %d\\circ', lambda, theta));
end
