[Multimedia Develop] SFTW351-Assignment1-D-A6-2776-4 DL : 0: * Zooming and Shrinking Images -(a) Write a computer program capable of zooming and shrinking an image by nearest neighbour and bilinear interpolation. The input to your program is the desired size of the resulting image in the horizontal and vertical direction. Then your program should create and display the resulting image in the desired size. Note: You cannot use the existing functions in the CImg library for zooming and shrinking. (b) Download the image (Fig2.19(a)) of size 512 x 512 and use your program to shrink this image to sizes 256 x 256 pixels, 100 x 100 pixels, and 30 x 30 pixels, using both nearest neighbour and bilinear interpolation. (c) Use your program to zoom each of the resulting images in (b) back to 500 x 500 with their respective interpolation methods. Explain the reasons for their differences from the original attached image.

[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.
