Mental health diagnosis of college students based on facial recognition and neural network.

In recent years, college campus incidents caused by mental health problems have been increasing year by year, and college students' mental health problems have become the focus of attention of schools, society and parents. Based on this, this paper proposes a facial emotion recognition method for college students. By using moving target detection, target classification, target tracking, and a series of image preprocessing techniques, this method achieves intelligent monitoring of the area where college students are located and can automatically alert when a potentially dangerous target is found. Moreover, this method uses a combination of shape features and motion features to select and extract feature quantities. In addition, the method calculates the similarity between the target and candidate target corresponding sub-models, and according to the ability of each feature to distinguish between the target and the background, monitors the student's mental health in real time and prevents various problems from occurring. Through experimental research, we can see that the model constructed in this paper has good performance. [ABSTRACT FROM AUTHOR]
