Abstract
First,hands are split from the background based on depth information from images got by the Kinect depth sensor.And then,three formulas are added to the Hu moment to make invariant moment contain more detailed characteristics for hand gesture recognition.At last,recognition results are translated into a control command which is transmitted to the intelligent wheelchair through Ad-Hoc network,to achieve motion control.Experiment shows that the gesture recognition achieved through this method has invariance all in images' rotation,zooming,panning,and is of strong robustness to background interference.
