Intelligence

Classroom Behavior Analysis

Supports student mode and teacher mode.
Student mode:
Head up detection, standing detection, heads up people counting, and close-up of standing students.
Teacher mode:
Supports up to 5 face databases and 10,000 face images. It offers abnormal number of people detection (for tracking teachers), back turned to students detection, walking detection, writing on blackboard detection, and performs face comparison of teachers.

Exam Behavior Analysis

Suport looking around and passing object detection

Face Recognition

Face recognition, track, priority, snapshot, face enhancement, face exposure
Face attribute extract, 6 attributes and 8 expressions: Gender, age, glasses, expressions (anger, sadness, disgust, fear, surprise, calm, happiness and confusion), mask, beard
Face matting setting: face, single inch photo
Two snapshot strategies: priority snapshot, recognition
Face angle filter
Priority time setting
Management of 5 group face libraries
Single person register and person register in batch
Face recognition and similarity setting
Max supports face contrast in face library with 100,000 faces
Support Duration Optimal
