在土工三轴试验中应用该方法使得试样的变形测量更加简便。通过使用高精度标定板，对该数字图像测量方 法进行了精度分析，结果表明亚像素角点检测方法的轴向和径向测量的标准差都达到了0．02个像素，相对测量精度达到10‘4 数量级。(Triaxial tests in application of this method makes it easier specimen deformation measurements. By using high-precision calibration board, the digital image analysis to measure the accuracy of the method, the results of the standard deviation to measure the axial and radial table Minya pixel corner detection methods have reached 0.02 pixels, relative measurement accuracy of 10 ' 4 magnitude.)

文件包含三个子文件：dec.m,test_dec.m,recon.m dec.m文件使用MATLAB语言自己动手编写小波分解算法； test_dec.m使用MATLAB语言测试dec.m文件中自己编写的小波Mallat分解算法正确性 recon.m使用MATLAB语言自己动手编写Mallat重构算法 函数使用MATLAB语言，没有调用MATLAB小波分解函数，而是自己动手编写的小波Mallat算法对含噪声的信号进行分解、重构；这对对小波分解的初学者，加深对小波分解有着引导作用。(The file contains three sub file: dec.m, test_dec.m, recon.m The dec.m file using the MATLAB language to write my own wavelet decomposition algorithm Wavelet Mallat test_dec.m using MATLAB language test in the dec.m file to write your own decomposition algorithm correctness Recon.m uses the MATLAB language to write my own Mallat reconstruction algorithm Function of the use of MATLAB language, do not call the MATLAB wavelet function, wavelet Mallat algorithm but prepare yourself for decomposition and reconstruction of signals containing noise this pair of wavelet decomposition for beginners, deepen their understanding of the wavelet decomposition has a guide role.)
