说明： 本论文包含5个源程序，分别为LSBCut、LSBCollage、DCTCut、DCTCollage和PSNR，其中LSBCut实现了LSB水印算法的剪切篡改的检测、LSBCollage实现了LSB水印算法的拼贴篡改的检测、DCTCut实现了DCT水印算法的剪切篡改的检测、DCTCollage实现了DCT水印算法的拼贴篡改的检测、PSNR功能是计算嵌入水印嵌入的峰值信噪比，以此来说明嵌入水印后图像载体的失真大小。LSBCut、LSBCollage、DCTCut、DCTCollage是独立的程序，每个程序独立完成一种篡改检测的功能且都有一个输出参数，没有输入参数，输出的参数是漏警概率。PSNR需要LSBCut、LSBCollage、DCTCut、DCTCollage产生的嵌入水印后的图像和原始图像作为输入参数，作为LSBCut、LSBCollage、DCTCut和DCTCollage的内函数使用。
(This thesis contains five source program, LSBCut, LSBCollage respectively, DCTCut, DCTCollage and PSNR, including LSBCut implements the LSB watermarking algorithm of shear tampering detection, LSB watermarking algorithm was realized LSBCollage collage tampering detection, DCTCut implements the DCT watermarking algorithm of shear tampering detection, DCTCollage implements the DCT watermarking algorithm of collage of tampering detection, PSNR function is to embed watermark embedding peak signal-to-noise ratio, in order to show that embedded watermark image carrier after distortion.LSBCut, LSBCollage, DCTCut, DCTCollage is independent of the programs, each program independently a tamper detection function and has an output parameter, no input parameters, output parameters are leakage alarm probability.PSNR need LSBCut, LSBCollage, DCTCut, DCTCollage of embedded watermark image and the original image as the input parameters, as LSBCut, LSBCollage, DCTCut and DCTCollage function in use.)
