- 音频的水印加入算法，采用matlab实现-joined audio watermarking algorithm, using Matlab to achieve
matlab
- 基于回声隐藏的信息隐藏算法，是一种音频信号的水印技术，包括隐藏信息的嵌入和提取，以及对于噪声，MP3压缩，滤波，重采样和延迟攻击的模拟。-Based on echo hiding information hiding algorithm, is an audio signal watermarking techniques, including embedding and extracting hidden information, as well as for noise, MP3 compr
watermarking
- 对音频信号分帧加窗,对每帧进行三阶小波变换,取其逼近系数平均值(一般为零).在此嵌入二值图像 并有对潜入水印信号进行盲检,恢复其嵌入水印-Sub-frame of the audio signal increases the Hamming window for each frame impletment third-order wavelet transform, whichever is close to the average coefficient (usually zero). a

- 音频添加水印的详细程序 源码 希望对大家有所帮助-Add audio watermark detailed procedures
steg1
- this program steganographs an image into another image. however the host and the specimen are image equivalents of audio signals which are rearranged to form an image. thus effectively it is audio steganography

- 最不 重 要 位(LSB)方法DO是将秘密数据(水印数据)嵌入到载体数据中最简单的一种方法，它是在时域里隐藏数据。任何的秘密数据都可以看作是一串二进制位流，而音频文件的每一个采样数据也是以二进制数来表示。这样，可以将部分采样值的最不重要位用代表秘密数据的二进制位替换掉，以达到在音频信号中嵌入秘密数据的目的。-The most significant bits (LSB) method of DO is the secret data (watermark data) embedded into
