这是我们的一次作业，图像添加水印，图像翻转等，希望有用(This is our first operation, image watermark, image flip in the hope that a useful)

: 针对实际振动位移难以获取的问题, 利用振动位移与加速度信号之间的关系, 先对采样后的加速度信 号采用时域数值积分,得到含有趋势项的速度信号及位移信号,再采用拟合多项式极值的方法, 消除积分过程 中产生的趋势项,从而得到更为精确的速度和位移信号. 算例表明, 利用拟合多项式极值消除趋势项的方法, 得到的位移时程曲线拟合精度高(: In pract ical engineering , the collection of displacement data is mo re dif ficult than that of the acceleratio n data in the time-domain .Displacement sig nals w as g ot f rom acceleration s ignals using aumerical integrat ion , wi th the t rend o f erro r.

从excel中提取数据，应用小波包分解提取特征频段能量值的matlab程序(Extracting data from excel, the wavelet packet is used to decompose the matlab program that can measure the value of the feature frequency)

cvlib_mex为封装了openCV重要函数的库，matlab可以直接调用文件从而运行openCV函数。压缩包中已包含cvlib_mex.mexw64文件，可以直接使用。PS:mexw64适用于windows下的64位matlab。(cvlib_mex important function to encapsulate the openCV library, archive already contains cvlib_mex.mexw64 files can be used directly. PS: mexw64 applicable under windows 64 matlab.)
