中文说明：基于知识库的手写体数字识别，教材配套代码，完整可直接运行！！！首先，读入手写数字图片进行图像归一化处理，统一尺寸，二值化；其次，对二值化图像进行图像细化等形态学操作，特征提取；最后，载入模板矩阵进行比对，选用欧氏距离测距，得到识别结果。
English Description：
Based on the knowledge base of handwritten numeral recognition, textbook matching code, complete, can run directly!!! First, read the handwritten digital image for image normalization, uniform size, binarization; second, the binary image for image thinning and other morphological operations, feature extraction; finally, load the template matrix for comparison, select Euclidean distance measurement, get the recognition results.
