11
Human Body Depth Image Can you recognize each body parts? Is it possible to computer?
12
Human Pose Recognition
13
Kinect Mainstream
14
Body Part Recognition 다양한 체형과 자세로 선행 학습
15
Human Joint Estimation 선행 학습한 데이터를 이용 새로 입력되는 데이터로 human pose 생성
16
Overview Kinect Kinect in Research Kinect in Medical
17
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
18
Research 앉는 동작 선행 학습 선 동작 선행 학습
19
Research Labeling issue
20
Research Joint estimation issue Labeling에 많은 noise가 있을 경우 일부 body part가 없 을 수 있다. Labeling에 실패한 body part에 대한 처리 과정 필요
21
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) : J oint estimation X probability with given model
