Evaluation of Classroom Teaching Effect Based on Facial Expression Recognition

Classroom is an important environment for communication in teaching events.Therefore,both school and society should pay more attention to it.However,in the traditional teaching classroom,there is actually a relatively lack of communication and exchanges.Facial expression recognition is a branch of facial recognition technology with high precision.Even in large teaching scenes,it can capture the changes of students’facial expressions and analyze their concentration accurately.This paper expounds the concept of this technology,and studies the evaluation of classroom teaching effects based on facial expression recognition.
