Semi_FragileAuthenticationWatermark
- 基于DCT压缩前后不变量,编写的抗JPEG压缩的数字图像认证水印算法,具有良好的抵抗压缩、剪切、篡改等性能的水印仿真程序-Around the DCT-based compression is not variable, the preparation of the anti-JPEG compression algorithm for digital image authentication watermark with good resistance to compression, shea
lsb-MATLAB
- 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
