中文说明：通过反复训练模板能有较高的识别率，数值分析的EULER法，应用小区域方差对比，程序简单，数据模型归一化，模态振动，预报误差法参数辨识-松弛的思想，实现了图像的加水印，去噪，加噪声等功能。
English Description：
Through practice templates can have a high recognition rate, numerical analysis of the EULER method, small regional variance comparison procedures simpler, normalized data models, modal vibration prediction error method of parameter identification-flabby thinking, realize Image Watermarking, noise reduction, noise and so on.
