DCT
- 图像加密的一种算法，DCT变换用于提取图像特征(The algorithm is used to encode picture, and use DCT transform)
Jsteg
- 基于DCT的jsteg图像隐写及分析算法，MATLAB实现。 JSteg的算法主要思想是将秘密消息嵌入在量化后的DCT系数的最低比特位上，但对原始值为O、1的DCT系数不进行嵌入。提取秘密消息时，只需将载密图像中不等于0、l的量化DcT系数的LSB取出即可。(The main idea of the JSteg algorithm is to embed secret messages in the lowest bit of the quantized DCT coefficients, b
DCT_F3
- 用MATLAB实现的 基于dct的f3隐写(the f3 steganography based on the dct with matlab)
水印
- dct变换嵌入水印并实现提取，最后测试三种不同攻击对水印的影响(The DCT transform embeds watermark and realizes the extraction. Finally, the influence of three different attacks on watermark is tested)
信息隐藏源代码
- 信息隐藏与数字水印实验源代码，lsb,dct,dwt等算法(Experimental information source code)
PicCompressEncode
- DCT效应-保留DC及前8个AC，在C#平台上制作表格显示(DCT effect - retains the DC and the first 8 AC, and produces tabular displays on the C# platform)
watermark
- 将具有特定标识的信息隐藏在数字化图像、视频、音频等多媒体。是一种基于DCT变换和ARNOLD置乱技术的数字图像水印算法，首先通过Arnold置乱二值水印图像对水印图像进行加密，其次将加密后的图像选择适合的强度，在载体图像中选择低频信号的位置进行嵌入。适合用于简单的图片版权保护。(Information that has a specific identity is hidden in digital image, video, audio and other multimedia. Is a k
