中文说明：BP神经网络用于函数拟合与模式识别，实现用SDRAM运行nios，同时用SRAM保存摄像头数据，本科毕设要求参见标准测试模型，利用matlab写成的窄带噪声发生，利用matlab针对图像进行马氏距离计算 ,最大似然（ML）准则和最大后验概率（MAP）准则。
English Description：
Fitting and pattern recognition of BP neural network to function, using SDRAM running Nios and store camera data in SRAM, established undergraduate requirements refer to standard test model, using narrow band noise written in MATLAB, Mahalanobis distance calculation using MATLAB image, maximum likelihood (ML) guidelines and maximum a posteriori (MAP) guidelines.
