用的db2小波对图像进行分解重构，小波函数可以换(wavelet analysis of figure by db2 )

说明：  实验目的 本次实验与书中第二章及3.2节的部分内容有关，包括以下几个部分： （1）开始使用MATLAB （2）显示图像，理解图像的模型 （3）使用图像的不同格式，理解图像压缩的意义 （4）对图像做简单的操作 本次实验需要熟练使用以下几个MATLAB命令： imread, imwrite, imshow,figure (Experimental purposes of this experiment with the book, chapter and part of the contents of 3.2, including the following sections: (1) start using MATLAB (2) show the images, understanding image model (3) the use of images in different formats, understand the significance of image compression (4) on the image to do a simple experiment needs to operate the skilled use of the following MATLAB command: imread, imwrite, imshow, figure)

回声隐藏利用人耳听觉系统的时域掩蔽特性，在载体数据的环境特性中嵌入水印信息(Echo hiding ear hearing system of time domain masking properties, environmental characteristics of the data in the carrier embedded watermark )

全相位陷波器是全相位数字信号处理体系中一个很有特色的技术，在通信、军事等抗强干扰场合中应用及其广泛，因而研究全相位陷波器并仿真建模实现其滤波功能，具有很高的意义。(All-phase notch filter is a very distinctive technique in the all-phase of digital signal processing system. In communications，military and such resistance interference are widely used. Therefore, it is of high significance to the study of All-phase notch filter and simulate the modeling to realize the filter function)
