2 - SVD Compression :
- compress images using SVD with different compression rate,and compare them
3 - DCT Compression :
- compress images using DCT with different compression rate,and compare them
4 - Facial Recognition with SVD
- extracting EigenImages
- Draw r_order approximation error graph
- construct r dimensional Feature Vector
- Draw accuracy chart using Linear regression to train
