函数逼近与曲线（面）拟合 种插值方法 数值微分 解线性方程组的直接方法(Function approximation and curve (surface) fitting kinds of interpolation method, numerical micro-decomposition of the direct method of linear equations)

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.
