Simplified skeleton model based hand gesture recognition

Abstract

There are two ways for 2D graphics recognition in general, which are contour curve description method and graphical Skeleton description method. Graphical Skeleton achieves recognition purpose by analyzing the relationship among the various parts of graphics. However, its performance is unstable, since it is very sensitive to contour noise. This paper adopts the graphical Skeleton description method to identify some commonly used number gestures, and introduces some approaches to optimize it for simplified gesture model. © 2013 Springer-Verlag.
