中文说明：手写体数字识别的基本过程：系统主要由手写体数字识别的训练过程和识别过程组成：，训练过程和识别过程均包括预处理、特征提取和模式识别三部分。一般包括如下过程：获取数据（用计算机来获取或显示数据）→预处理（去噪声，提取有用信息，对其他因素所造成的退化进行复原）→特征提取(对待测数字提取明显特征，与样板进行比较)→选择分类→识别输出（输出最终数字）。
English Description：
The basic process of handwritten numeral recognition: the system is mainly composed of handwritten numeral recognition training process and recognition process: the training process and recognition process include preprocessing, feature extraction and pattern recognition. Generally, it includes the following process: data acquisition (data acquisition or display by computer) → preprocessing (noise removal, extraction of useful information, restoration of degradation caused by other factors) → feature extraction (extraction of obvious features from the digital to be measured, comparison with the template) → selection of classification → recognition output (output of final digital).
