Design of Teaching Attendance System Based on Image Processing

Traditional classrooms often require teachers to roll call one by one in class, which not only affects the length of the class but also affects the quality of the class, and there is no timely data feedback, resulting in the lag of the work of many college students.This topic mainly uses computer simulation software for algorithm research, which is mainly divided into four parts, the first is the initial establishment of the face library, the second is the use of PCA algorithm for face image dimensionality reduction in face recognition, the Euclidean distance is used again for face closest matching, and finally the function is realized by GUI interface.
