4 Introduction Video-based behavior analysis for ADHD diagnosis in children between 8-11 years. 4

5 Introduction Behavior analysis  Human pose information along time 5 Head Body Hands time Gestures Inattention Hyperactivity Impulsivity 1. Data acquisition 2. Feature extraction: Human Pose 3. Gesture detection

6 Outline 1.Introduction 2.Methodology 1.Data acquisition 2.Feature extraction 3.Gesture detection 3.Results 4.Conclusion 6

7 Data aqcuisition 7 Microsoft’s Kinect RGB + Depth Invariant to color, texture and lighting conditions Human pose directly obtained

8 Feature extraction: Human Pose 8 RGB + Depth Body skeleton 42-dimensional vector: 14 joints × 3 spatial dimensions
