指示手势的手指尖定位方法
摘要：
本发明涉及一种指示手势的手指尖定位方法。它是根据指示手势行为中的指示手势的手部特征，自动确定指示手势的手指尖位置。采用背景差分法，提取指示手势对象，运用肤色分割方法，提取指示手势的手部区域，根据指示手势的手指尖位于指示手势的手部边沿轮廓且距离指示手势的手指区域重心最远处，自动确定手指尖点。从而快速有效地定位指示手势的手指尖点位置，满足指示手势人机交互中的特征提取要求。
摘要（英）：

The invention relates to a method for positioning finger tips of directed gestures. In the method, the positions of the finger tips of the directed gestures are automatically determined according to the characteristics of hands of the directed gestures in directed gesture actions. A background difference method is adopted to extract objects of the directed gestures, a complexion partition method is used to extract a zone of the hand of the directed gestures, and a finger tip point is automatically determined according to a position of the finger tip of the directed gestures which is positioned at the outline of the edge of the hand of the directed gestures and farthest from the zone of the finger tip of the directed gestures. Therefore, the invention fast and effectively positions the position of the finger tip point of the directed gestures, and meets the requirements for extracting features in human-computer interaction of the directed gestures.
