Final project for "Metodi del Calcolo Scientifico" course. The assignment is divided in two parts:
Implement the DCT2 algorithm without quantization and compare it with an open-source implementation which uses the FFT.
The code for this part is stored in the custom-dct directory.
Write a GUI program to load grayscale bitmap files and compress them with DCT2 based on two parameters: F (block size) and d (frequency limit).
Original and compressed image has to be shown side by side to allow an easy comparison.
