Image compression with DFT in matlab

Image compression using a discrete Fourier transform in matlab. We can compress a lot and still have excellent picture. I.e. drop ratio of 70% and still good quality.

Note: I will not upload matlab code, this was done for a class assignment. The code is not important, it’s the method. If interested, you should check out CS 370 Numerical Computation from University of Waterloo. I’m leaving the lecture notes link here: https://cs.uwaterloo.ca/~kogeddes/cs370/cs370_notes_f08.pdf
