Kinect and its Application Movement Research Lab Kyungyong Yang
Overview • Kinect • Kinect in Research • Kinect in Medical
Kinect Commercial • http://www.youtube.com/watch?v=T_QLguHvACs
How to • 3D Motion Capture • 3D Surface Scan • Depth Camera • Etc…
Depth Camera Depth Image RGB Image
How Kinect Works • Evaluate near-infrared reflection time • Create accurate depth map
Human Body Depth Image • Can you recognize each body parts? • Is it possible to computer?
Body Part Recognition • 다양한 체형과 자세로 선행 학습
Human Joint Estimation • 선행 학습한 데이터를 이용 • 새로 입력되는 데이터로 human pose 생성
Overview • Kinect • Kinect in Research • Kinect in Medical
Research • Issue • 잘 동작하게 하기 위해서 많은 예제를 사전학습 해야 한다. • 데이터를 무한정 늘릴 수 없으므로 선정이 중요하다. • 중복되지 않으면서 부족한 예제가 없도록 만들자 • Data의 uniform sampling이 필요
Research • 앉는 동작 선행 학습 • 선 동작 선행 학습
Research • Labeling issue
Research • Joint estimation issue • Labeling에 많은 noise가 있을 경우일부 body part가 없을 수 있다. • Labeling에 실패한 body part에 대한 처리 과정 필요
Research • Use bayesian estimation • P(X|Z) = max( P(X|X’)P(X’|Z’) ) P(Z|X) P(X) • P(X|Z) : Joint estimation X probability with given labeling Z • P(X|X’) : Transition probability from X’ to X • P(X’|Z’) : Last joint estimation probability • P(Z|X) : Labeling probability with given joint estimation X • P(X) : Joint estimation X probability with given model

Medical Application • 수술실에서 오염되지 않고 기기를 자유롭게 제어할 수 있다. • 스페인 Tedesys수술실 • 의사들이 손 동작을 통해 MRI 및 CAT 스캔 영상 제어.

Fitness Trainer Application • http://www.youtube.com/watch?v=2tSNsb7l0AM
홈 재활운동 트레이너 • 꾸준한 재활 운동이 필요한 환자 • 매일 의사나 전문가가 체크하기 어려움 • Kinect를 이용한 자가 재활운동
Conclusion • At the research viewport • Kinect is very strong depth input device. • At the development viewport • Kinect is very strong motion controller. • At the medical viewport • Kinect is some aid.
