In the process of human computer interaction, hand tracking is of great importance. A practical hand tracking method based on improved particle filters with elliptical region covariance descriptors is proposed. Firstly, an elliptical tracking window containing the hand is determined manually in the initial frame. Based on the HSV color model, the color feature of bare hands is extracted, and color...
In the process of human computer interaction, hand tracking and hand gesture recognition are of great importance. Hand segmentation is the first step of hand gesture recognition. Among several common methods, the background subtraction method is chosen for detecting moving hands. An improved Gaussian mixture model is used to establish the background model. In order to adapt to a changing scene, parameters...
