Description: 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.
