数字音频水印程序 基于小波变换的嵌入提取程序(water shuiyin)

在对一组离散数据点进行拟合时，我们采用最小距离拟合来达到拟合的函数与原数据达到最优拟合(In a group of discrete data points to fit, we use minimum distance fit to achieve the fit function to achieve optimal fit with the original data )

用于仿真高斯噪声、单音干扰、多音干扰以及不同占空比下干扰条件下的扩频系统性能及误码率(For the simulation of Gaussian noise, single tone interference, spread spectrum system performance in multi-tone interference and interference under the conditions of different duty cycles and bit error rate)

there are two parts in these codes. the first implements an eight point algorithm which is used to compute the fundamental matrix in computer vision. the second is used to compute the optical flow and the unreliable region.

包括两个文件，一个RLS、一个多维RLS算法matlab程序。(Consists of two files, one RLS, RLS algorithm matlab a multidimensional process.)

只是一个数字水印的小程序，希望能给大家一些帮助(digital watermark)

这是一个模糊算法的框架，只需修改模糊规则表，就可以移植到自己的工程中。(This is an algorithm of fuzzy algorithm framework, only need to modify the fuzzy rules table after can be transplanted to their own project.)

进行波形数据分析,数学方法是部分子空间法，可以得到很精确的幅值、频率、相位估计。( Waveform data analysis, Mathematics is part of the subspace, You can get a very accurate amplitude, frequency, phase estimation.)
