主要介绍基于dct的数字音频水印，以及水印的嵌入和水印的提取(Introduced digital audio watermarking based on dct, and the watermark embedding and watermark extraction)

this is a source code for contours detection.

几种常用分布（如泊松分布、正态分布、指数分布、均匀分布）随机变量的matlab实现方法。(Surement distribution (eg Poisson distribution, normal distribution, exponential distribution, uniform distribution) random variable matlab implementation methods.)

MUSIC算法[1]是一种基于矩阵特征空间分解的方法。从几何角度讲，信号处理的观测空间可以分解为信号子空间和噪声子空间，显然这两个空间是正交的。信号子空间由阵列接收到的数据协方差矩阵中与信号对应的特征向量组成，噪声子空间则由协方差矩阵中所有最小特征值（噪声方差）对应的特征向量组成。(MUSIC algorithm [1] is a feature space based on matrix decomposition method. From the geometric point of view, the signal processing can be decomposed observation space the signal subspace and the noise subspace, it is clear that the two spaces are orthogonal. Signal Subspace data received by the array covariance matrix and eigenvectors corresponding to the signal component, the noise subspace from the covariance matrix of all the smallest eigenvalue (noise variance) eigenvector components.)
