[matlab] vi2 DL : 0: 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.

[Special Effects] C DL : 0: 运用matlab对图像进行放大：像素复制法和双线性插值法。像素复制方法的图像缩放的原理主要是对原来输入图像的整行或是整列像素进行简单的复制与删除，达到改变图像大小的目的。双线性插值放大算法中，目标图像中新创造的象素值，是由原图像位置在它附近的小区域象素的值通过加权平均计算得出的。-Write MATLAB function to zoom a grayscale image from original size to the given output size through two different methods: a) pixel repetition and b) bilinear interpolation. Zoom the images processed in the Task 2 back to the original size using above mentioned methods. Calculate MSE and PSNR for the original and zoomed images using MATLAB methods written for the Task 1. Plot the MSE and PSNR as function of the size reduction ratio respectively. Define what combination of shrink/zoom methods provides the minimal MSE and maximal PSNR for the same size reduction ratio.
