MIME: A Video Based Hand Gesture Interface.
As computing power and imaging technology have become much more accessible in recent years, it is now possible to bring tangible benefits from image processing to the desktop - to change the way you work with your computer. Using a single video camera positioned near your display, MIME (Mime Is Manual Expression) allows you to use intuitive hand gestures to control your computer and escape the tangle of mice and keyboards.
The MIME system is a process for recognizing hand gestures captured using a video camera and a standard consumer personal computer. Initially developed and implemented using the MATLAB mathematical environment, the system is designed for implementation in C code for the Microsoft Windows environment allowing real- time gesture control of new and existing applications.
Using a novel two-dimensional model of the human hand, MIME employs a efficient, single-pass algorithm to segment a hand and extract its model parameters from each frame in the video input. The hand is tracked from one frame to the next using a constant-acceleration Kalman filter approach. Tracking and feature extraction is robust and efficient.
