假定训练样本图像为picture1，待识别的图像为picture2。 1. 样本训练
（1).对图片picture1进行特征提取，得特征向量data_in[][]. (2).把特征向量data_in[][]送人BP网络进行训练，保存输入层与隐层之间的权值到win.dat中，保存隐层与输出层之间的权值到whi.dat中。 （3）。显示训练结果，如训练成功转字符识别，不成功则继续训练。 2.字符识别 （1）。对图片picture2进行特征提取，得特征向量data_in[][]
(2).读取win.dat和whi.dat中的信息分别到*input_weights和hidden_weights之中。 （3）将data_in[][]送入BP网络的输入层*input_unites.
（4）将*input_unites和*input_weightts送入BP网络中进行前向输入激活。得到*hidden_unites.再将*hidden_unites和*hidden_weights送入BP网络中进行前向输入激活得*output_unites.其实*output_unites存放的是out[][6]相关内容，即待识别样本的输出结果。 (5)。对*output_unites进行识别，如果output_unities[i]大于0.5.则判断其值为1；如果output_unites[i]小于0.5.则判断其值为0；再对其求加权值，如output-unites[]=(0.1,0.1,0.9,0.1,0.1,0.9),则待识别字符为\。即25×0＋24×0＋23×1＋22×0＋21×0＋20×1=9 合理性分析
