Abstract:
In this paper,a camera face recognition method based on PTZ (Pan,Tilt,Zoom) is proposed.In this method,the motion parameters of PTZ camera are retrieved based on the face center position coordinate and the PTZ camera rotates.With the rotation,the face center and the camera viewing field center overlap.Then the combined face characteristics extracted from geometric characteristic and PCA (Principal Component Analysis) are used as the face recognition characteristics.The camera effective recognition range is improved through reducing the influence of face attitude and position.Experiment results show that the method can reduce the scarcity of a single feature for face recognition,improve the effective recognition rate significantly with a wide distance range.
