【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.

【Special Effects】 sc3 DL : 0: 通过观察图像lena_noise.bmp可以看到，该图像主要包含高斯噪声、椒盐噪声等。通过查阅资料可知，维纳滤波可以很好的滤除高斯噪声，而中值滤波对于椒盐噪声的滤出效果优异，因此本次采用维纳+中值的滤波方式进行图像的去噪处理。图像常用评价方法有：信噪比、相关系数、清晰度。信噪比较为常用；相关系数由于滤波会使原图像失去某些细节，因此这种评价方式为参考性指标而非绝对评判标准；清晰度为图像子块的方差综合考虑采用图像的峰值信噪比(PSNR)作为评价去噪效果指标(自编PSNR.m函数).-By observing the image lena_noise.bmp can see that the image consists mainly of Gaussian noise, salt and pepper noise. Through access to information shows that the Wiener filter can be well filtered Gaussian noise, and median filter for impulse noise filter out excellent results, so this value using Wiener filtering method+ in image denoising. Image evaluation methods commonly used are: noise ratio, correlation coefficient, clarity. SNR is more commonly used correlation coefficient as filtering the original image will lose some of the details, so this evaluation method as the reference index rather than absolute criteria clarity of image sub-block variance considering the peak signal using image noise ratio (PSNR) as an evaluation index denoising (self PSNR.m function).
