Motion capture

Motion capture is the process of recording high-resolution movement of objects or people into a computer system. It is used in military, entertainment, sports, medical applications, and for validation

Gesture recognition
Videos
Gesture recognition is an area of research and development in computer science and language technology concerned with the recognition and interpretation of human gestures. A subdiscipline of computer
Some alternative methods of tracking and analyzing gestures, and their respective relationships
A real hand (left) is interpreted as a collection of vertices and lines in the 3D mesh version (right), and the software uses their relative position and interaction in order to infer the gesture.
The skeletal version (right) is effectively modeling the hand (left). This has fewer parameters than the volumetric version and it's easier to compute, making it suitable for real-time gesture analysis systems.
These binary silhouette(left) or contour(right) images represent typical input for appearance-based algorithms. They are compared with different hand templates and if they match, the correspondent gesture is inferred.
