a system for skin color morphology in video that can detect face based on skin color

这是用COSTAS环在接收端提取载波的例子，可以用，特别适合初学者，理解COSTAS环的(This projiect is about costas and it can be used to get the receive frequency.)

基于小波包分解的语音去噪，根据熵谱概率密度函数估计阈值，去除实际环境噪声。(Based on wavelet packet decomposition of the voice de-noising, in accordance with spectral entropy probability density function estimated threshold, the actual removal of environmental noise.)

在度量两个矩阵时，快速的度量函数能有效地提高检索效率，在此采用EMD度量函数(In the measure two matrix, fast measurement function can effectively improve the retrieval efficiency, in this the EMD measure function )

说明：  求x的算术平方根，保留N位有效数字，并返回算术平方根的平方(solving the square root of x with N digits Significant figures, and saving the Square root of the square)

在保密数据传递等应用中，有时采用将一句话或一段文字或一段音乐隐藏在另一段音乐中，然后利用专门的算法来提取所传的信息(Data transfer in applications such as security, sometimes using the word or a text or a piece of music hidden in another section of music, and then use a special algorithm to extract the information transmission)
