vi2
This program compress and recostruct using wavelets. We can select level of decomposition(here maximum 4 levels are given) of images using selected wavelet.
For eg:-wavelets can be haar, db1, db2,dmey...............
Decomposition can be viewed in figure.
(Please note that select 256X256 image for better result.)
Then compression can performed,
PERFL2 give compression score.
Then reconstruction can be performed.
Each decompsition we can choose different threshold values.
For each threshold value we can calculate mse,psnr,pq(picture quality),
bit ratio etc. To get pq install pqs function . (This program compress and recostruct using wavelets.

散傅里叶变换的性质
一、 实验目的
1、 掌握离散傅里叶变换的性质，包括线性特性、时移特性、频移特性、对称性和循环卷积等性质；
2、 通过编程验证傅里叶变换的性质，加强对傅里叶变换性质的认识。
(The nature of the discrete Fourier transform, the purpose of the experiment 1, to grasp the nature of the discrete Fourier transform, including a linear characteristic, when the shift characteristic frequency-shift characteristic, symmetry, and the circular convolution nature 2, through the programming verification Fu li the nature of the Fourier transform, to enhance the understanding of the nature of the Fourier transform.)
