Thanks

[@hibiscae]

thank you so much for explaining it properly. my professor speaks too fast and is not making sense well to my end. but ik that your series of image processing will help me a lot.

[@ZEISS_arivis]

You're very welcome! Everyone has different way to learn and I am glad my teaching method matches your learning style.

Excellent tutorial!
Thank you so much for your efforts.
However, one clarification: Isn't edge detection done using a high pass filter and not a low pass filter?

[@ZEISS_arivis]

Yes, low pass filter smooths images and high pass filter sharpens the edges. I didn't realize that I misspoke. Thanks for letting me (and others) know.

[@santiagoseppi2946]

Hello. If I have a numpy complex array, can I use cv2.dft too, or should it be a float array?

[@ZEISS_arivis]

Not sure off top of my head, you have to check the documentation for opencv.
