中文说明： 二维Gabor滤波器具有优良的空间局部性和方向选择性，能够抓住图像局部区域内多个方向的空间频率和局部性结构特征，可以看作是一个对方向和尺度敏感的有方向性的显微镜。有源程序和子程序，自己可以学习和完善。
English Description：
&The two-dimensional Gabor filter has excellent spatial locality and directional selectivity. It can grasp the spatial frequency and local structure features of multiple directions in the local region of the image, and can be regarded as a directional microscope sensitive to direction and scale. Source program and subroutine, they can learn and improve.
