Practical implementation of a hand gesture recognition application for use in human-computer Interaction
Journal Title: Romanian Journal of Human - Computer Interaction - Year 2014, Vol 7, Issue 3
Abstract
The task of hand gesture recognition is actively researched and challenging because of complex backgrounds, different lighting environments and unpredictable hand movements. This paper presents an analysis along with an implementation of a system that can recognize the hand center, the fingers and the hand wrist. Hand center recognition is done by finding the minimum inscribed circle in the hand contour. Fingers are detected using the k-curvature algorithm. The hands positions along a trajectory are analyzed and based on those a general direction is established. The features are tracked in time using Kalman filter in order to achieve robustness in use and have stability in the features locations. The hand gestures are made out of a desired direction and a certain positioning of the fingers. An analysis is performed on three levels with the purpose of: quantifying the robustness of the system to lighting and background, determining the error rate and the processing rate.
