Video Analysis Of Classroom Teaching Activities For Wisdom Education

The development of information technology has a profound impact on all aspects of the society.Specifically,in the field of education,information technology has developed from its initial supporting role to make education information-based and intelligent,thus leading to the change of education mode,and thus the establishment of intelligent education.The development of communication technology and the Internet has greatly increased the number of network videos and brought a large number of classroom teaching videos.Now,the evaluation and evaluation of teachers are largely based on teaching videos,which greatly reduces the cost of time and space.The development of smart education has also brought about new teaching models.In recent years,heuristic education studies such as flipped classroom have become very popular.However,according to the current educational situation and China's national conditions,the traditional teaching model is still the main body of classroom education.Focusing on undergraduate education,this paper designs a set of information tracking method for interactive activities of classroom teaching based on video data,which has certain practical significance.For undergraduate students,the general format includes general lectures,seminars,and experiments.Ordinary teaching interaction activities mainly for teachers and students to question and answer session,for this part designs a 2 dpca + PCA + face recognition method of SVM identification of the main interaction,in order to improve the accuracy of identification on the basis of the introduction of the concept of global competition and random draw generalization the harmony search algorithm in complex nonlinear support vector machine(SVM)model of multi-optima parameter optimization ability.At the same time,speech recognition is carried out for the interactive content of the common teaching mode,and the recognition effect of the interactive subject is further improved through the speech information.Form for the seminar with experiment,using the camera Angle space perspective to zoning,use the regional per frame of pixel values reflect the student interaction activity,again through the target detection technology in the video to the student movement track,make on the degree of active area students reflect accurately to each student,student seminar discussion for judge its result provides a certain reference.
