The diagram presented here is a program flowchart showing the workflow of a project. According to the flowchart, we can see that after the student takes a snapshot, face detection will be done to the image, and the clear face image will be sent to the Gray Scale Image and be gone through face recognition. Then the student ID will be sent for recording attendance and a student attendance report will be generated. More details about the program can be learned on the flowchart.
