BimomentNormalization

代码说明：

  该算法是bimoment非线性归一化的改进，可以对最终的识别率有所提高，而且该算法能够自动的调整汉字的中心，并有很强的抗干扰能力(The algorithm is non-linear normalized bimoment improvements can eventually improve the identification rate, and the algorithm can automatically adjust the center of Chinese characters and has a strong anti-interference ability)
