Research on Student Face and Key Point Detection Based on Improved SSD Algorithm
This paper proposes a more suitable facial and facial key point detection model for classroom students.Be-cause the students in the back row of the classroom are small targets,in order to accurately detect the students in the back row,this paper fuses the three feature maps of the front end of the network to improve the detection ability of the network to small targets.According to the characteristics of students'facial physiological structure,the generation ratio of prediction box is improved.In order to verify the advancement of the algorithm,this paper designs a comparative experi-ment.The model proposed in this paper performs best on three difficult data sets.
