Doe-Hyung Lee and Kwang-Seok Hong, “Game interface using hand gesture recognition,” in 2010 5th International Conference on Computer Sciences and Convergence Information Technology (ICCIT) (presented at the 2010 5th International Conference on Computer Sciences and Convergence Information Technology (ICCIT), IEEE, 2010), 1092-1097.

Info:
1. The body motion recognition give the general user a sense of reality and immersion, help children and elderly to control devices more easily and intuitively.
2. Among the intuitive and simple methods, hand motion is becoming the most popular.

Methodology:
1. Stereo image input
2. Hand region detection - depth map calculation - remove background after recognize foreground - remove lighting error by histogram equalization (b4 that, apply gray image to differentiate between light and shade).
3. Pattern recognition - comparing image entropy with feature model.
