基于逆系统法的荷载识别程序，对于模型简单的识别效果较好(Based on the method of inverse system load identification procedures for the simple model, good recognition effect)

伪zernike矩变换，计算图像的伪Zernike矩并作为特征。(Pseudo zernike moment transformation, the image of the pseudo-Zernike moments calculated as features.)

非常好的中文资料关于名matlab编程序方面的。很好的资料要快(Very good information on Chinese matlab series of procedures. Very good information to be fast)

以MATLAB將影像做色彩空間轉換， 轉換的色彩分別為RGB轉Gray scale, RGB轉YUV, RGB轉lab, RGB轉HSV(MATLAB will do to the image color space conversion, the conversion of RGB colors were transferred Gray scale, RGB turn YUV, RGB turn lab, RGB and HSV)

this is simple qpsk for matlab code
