Frequency Domain Image Compression and Filtering
Over 4 years ago I wrote a short blog post on images in the frequency domain: https://blog.demofox.org/2016/07/28/fouriertransformandinverseofimages/ It’s time to revisit the topic a bit and add some more things. If you are curious about how the Fourier transform works, which can transform images or other data ...
