Description: 此程序用C语言求取彩色图像的PSNR。psnr是一种评价图像的客观标准。它具有局限性，PSNR是“PeakSignaltoNoiseRatio”的缩写。peak的中文意思是顶点。而ratio的意思是比率或比列的。整个意思就是到达噪音比率的顶点信号，psnr是一般是用于最大值信号和背景噪音之间的一个工程项目。-This program uses the C language to strike a color image PSNR. psnr is an objective criteria to evaluate image. It has limitations, PSNR is "PeakSignaltoNoiseRatio," the abbreviation. the peak of the Chinese meaning is the vertex. The ratio of the mean ratio than the column. The means to reach the vertex of the noise ratio signal, and psnr is generally used for a project between the maximum signal and background noise。 Platform: |

Instructions:
In Matlab, call the file DCTwipe . It should be done like this:
[wiped,wipedflags,PSNR]= DCTwipe(im,lumaQtable)
or
[wiped,wipedflags,PSNR]= DCTwipe(im,lumaQtable,chromaQtable)
INPUTS:
im- Image file to be anti-forensically modified. This should already be read into Matlab using imread. It can be either black and white or full color.
