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

2. 手动实现
