I came across Fourier coefficients and my understanding is that it is very efficient in analysing image properties such as shape etc.. I know we can use Fourier descriptors to describe shape... But in particular, I have a doubt can we extract lines and curves from a canny edge image using Fourier coefficients?

Thanks a lot!

  • $\begingroup$ I have the same doubt as you. A line corresponds to very localized information. Not what represent Fourier coefficients $\endgroup$ – Damien Dec 26 '18 at 8:03
