Book recommendations on Gabor filter and Fourier series I'm starting to learn about Gabor filters and Fourier series. I need to make a presentation on Gabor filters in a few months, so I need quality references for the presentation.

Does anyone have any suggestions on introductory books, useful articles or other similar literature which I may use as references for theory on Gabor filters and Fourier transform?
This is a book that I would recommend as a starting point: Richard Szeliski: Computer Vision: Algorithms and Applications
