图像 denoisig 自适应小波包阈值函数
图像去噪的统计优化的自适应小波包 (WP) 阈值函数基于广义高斯分布。它适用于噪声的图像,以获得最佳的树或最优小波基,利用信息熵计算高效多级 WP 分解。它选择自适应的阈值,即水平和子带依赖分析子带系数的统计参数的基础。在利用的阈值函数中,基于最大后验概率估计,每个系数和相应的子带的均值之间的最优线性内插法估计占主导地位的系数修改后的版本。实验结果表明,在不同噪声强度条件下的几个测试图像表明提出的算法,称为公开进修学院-收缩,产生更好的峰值信噪比和卓越的视觉图像质量 — — 通用图像质量指标用来衡量 — — 相对于标准的去噪方法,特别是在高噪声强度。它也优于一些最佳状态的现行基于小波变换的去噪技术。

MP3-watermarking
说明: :针对MP3 编码方式和帧结构进行分析,利用帧中的比例因子提出了一种压缩域水印算法。算法通过引入帧变化分析步
骤,很好地实现了水印的自适应嵌入。对于不同的系统要求,还可以通过修改门限信噪比的值SNRlim按需进行水印嵌入,使算法
具有更大灵活性。同时在牺牲一定的嵌入空间前提下,实现了水印信息的自同步。实验表明,对于不同风格的音乐,该水印算法
具有很好的不可听性。(In this paper,the encoding method and the frame structure of MP3 are expounded in detail,a watermark algorithm
is proposed based on the scale factor in MP3 frame.By introducing the step of frame altering analysis,the algorithm
can realize that watermarks is embedded adaptively.By modifying threshold SNRlim(the ratio of signal to noise),the algorithm
can meet different requirements of some system,that is what enable the algorithm to have a bigger flexibility.Based on expense
of some embedding positions,the watermark can be embedded with self-synchronization.The experiment results show
this algorithm can get a good audio effect with various types of audio.)
