Improvement of the real-time gesture analysis by a new mother wavelet and the application for the navigation inside a scale-one 3D system
TypeCommunications avec actes
This paper proposes a navigation technique for traveling inside a real-scale 3D model based on human gesture analysis. In the ﬁrst step, a simple threshold is used as a criterion to analyze gestures. In the next step, a complex criterion will be imposed to the analysis to improve the navigation technique. Walking is a periodic signal and moving feet up and down is a part which is repeated. A mother wavelet is allocated to the selected pattern. Then the position of the pattern is recognized by applying Multi Resolution Analysis (MRAs). The movement command is generated and sent to the graphic render (as a movement command). Analytical results show a very high precision performance in the presence of noise, scale variation and superposition of other signals. Practical experiments also verify the same promising results.
