Fourier image compressor has the view compressed function that allows users to see the intermediate stage of an image after it has been compressed using Fourier methods but before it has been decompressed. Fourier methods are techniques for compressing images based on transforming them into frequency domains using Discrete Fourier Transform (DFT) or Discrete Cosine Transform (DCT). The app’s function shows users how the image looks like after some of the smallest frequency coefficients have been discarded and not stored.
This function is useful for users who want to understand how Fourier methods work and how they affect image quality. It also allows users to compare the original image with the compressed and decompressed versions. The view compressed function is designed to provide users with a visual insight into Fourier compression and decompression.
