MATLAB Assignment 6: (CHANGE: this is no more a necessary assignment.)
Imaging and 2D wavelets:
The assignment is
- take an image (2 standard samples 256x256 are provided below)
- decompose it into 3-4 stages
- compress it 25, 50, 75% (or other values if you have curiosity)
- compose it back and compare (use relative error graph and just
print them out for comparison too)
- Use basis D2(Haar), D4, D6, D20(or something similar), Shannon and Fourier.

For sample compressed graphs
click here
(the compression is 50%, using Shannon, D6 and Fourier bases)
For sample sound files
click here
handel100.wav means no compression (100% coefficients are
saved, i.e. the original file);
handel25.wav means 25% of coefficients saved
