DICOMDIR

采用功率谱方式并用AR线性滤波方法生成脉动风速时程数据，能用于结构风载荷的计算。(Using power spectrum and AR linear filtering method to generate fluctuating wind speed time series data, can be used in structure wind load calculation.)

数字信号处理：基于计算机的方法 数字信号处理经典教材(Digital signal processing: a computer-based method for digital signal processing classic textbook)

基本图像处理，包括灰度处理、二值化处理、加噪声、去噪声、边缘提取等功能。(Basic image processing, including gray-scale processing, binarization processing, plus noise, to noise, the edge extraction function.)

说明：  在MATLAB上所使用的PCA程序，主要應用於過濾相對較不重要的特徵值(dimension)，例如在三度空間的某些點具有(x,y,z)值，因為這些點有共同的一個持徵，就是z值相對於x,y值來得小很多(不明顯)，所以就以X,Y軸來表示這些點。此時就達成去除掉z的特徵值(dimension)。 (MATLAB used in the PCA procedure, mainly used in filtering relatively unimportant eigenvalue (dimension), for example, in some points with three-dimensional (x, y, z) values, because these points have a common one sign holders, that is, z values compared with the x, y values much smaller than (not obvious), so on to X, Y axis to express these points. Reached at this time to get rid of z eigenvalues (dimension).)

构建自己的subplot函数，比matlab好用多了，自由控制(Build your own subplot function, easy to use more than matlab, free control)
