摘要： Device and method for tracking human face are provided. The device may include an image collection unit to receive a video image and output a current frame image included in the received video image to a prediction unit, the prediction unit to predict a 2-dimensional (2D) position of a key point of a human face in a current frame image output through the image collection unit based on 2D characteristics and 3-dimensional (3D) characteristics of a human face in a previous image obtained through a face fitting unit, and to output the predicted 2D position of the key point to the face fitting unit, and the face fitting unit to obtain the 2D characteristics and the 3D characteristics by fitting a predetermined 2D model and 3D model of the human face based on the 2D position of the key point predicted by the prediction unit using at least one condition.
