I was reading a paper which uses a filter bank of gabor filters with different frequencies and orientations. However, I often see the construction of a filter bank of gabor filters with different frequencies and scales.

I am not sure on the construction of it. How do I construct it, any generic example will be ok. Thanks!

Look on wikipedia. https://en.wikipedia.org/wiki/Gabor_filter The $\theta$ controls the orientation.
