grid-study 学习文件，提取特征值写入features.txt 文件



recognition 识别文件，记录错误到 log.txt



features.txt 为10*49 特征值



log.txt 为识别错误记录



study.txt 为学习图片的正确值



test.txt 为测试图片的正确值-grid-study learning file, extract the eigenvalue write the features.txt file recognition to identify file records error the the log.txt features.txt is 10* 49 eigenvalues ​ ​ log.txt recognition errors recorded the study.txt the correct value for learning picture test.txt is the correct value of the test images
