同态滤波法、希尔伯特法、香农法求取心音信号包络的matlab算法-The homomorphic filtering Law Shannon Hilbert method of calculating the heart sound signal envelope Matlab algorithm

采用傅里叶变换和数据矩阵平衡将同状态的波进行放大。 -Fourier transform and data matrix with the state of equilibrium will wave amplification.

这是同态滤波程序的改进版 待处理的图像以程序调用参数的方式输入，或者打开程序后输入 随后会依次出现两个调节框（一个调节完毕后关闭图片，会自动打开下一个调节框） 调节完毕后关闭调节框，程序会自动保存。-This is an improved version of homomorphic filtering program Image to be processed in order to program call parameters be entered, or enter th

有一类特殊的非线性系统，它遵从广义的叠加原理。在代数上，这类系统用输入和输出的矢量空间之间的线性变换来表征，因而称为同态系统。-A special class of nonlinear systems, which comply with the broad principle of superposition. In algebra, such systems use linear transformation vector space between the inputs and outpu
