Face Recognition Using an HD PTZ Camera in a Virtual Classroom

Madhavi VikramProf. Balaji Hariharan

Introduction

• Face Recognition, a kind of biometric software is a hotspot in computer vision technology

• It has many real world applications namely video surveillance, security checks in banks, airports and many more

• One of its most popular applications is in virtual classroom

Conclusion

• A face recognition system that gives the details of the student in a virtual classroom is designed

• Whenever the student raises hand for a doubt, the PTZ Camera which is used to monitor the student in the classroom is zoomed to the particular student to capture the student images and display the student name and student ID along with the face of the student

• The experimental results show that a better and interactive education system has been designed for the learners in a virtual classroom

Future Work

• More students can be considered for the study• Recognizing multiple students who has raised

hand for a doubt, also include database of students with varying pose and identify new faces not included in the database and add it to the database
