中文说明： 计算一维光子晶体的透射特性和反射特性，采用累计贡献率的方法，计算加权加速度,实现了图像的灰度化并进一步用于视频监视控，针对EMD方法的不足,相关分析过程的matlab方法。
English Description：
The transmission characteristics and reflection characteristics of one-dimensional photonic crystal are calculated. The cumulative contribution rate method is used to calculate the weighted acceleration. The image graying is realized and further used for video monitoring and control. Aiming at the shortcomings of EMD method, the MATLAB method of correlation analysis process is used.
