A FACE TRACKING METHOD AND DEVICE

摘要

PURPOSE: A face tracing device and a method thereof are provided to firstly obtain a key point location traced through operation prediction of a face, thereby increasing face trace processing speed. CONSTITUTION: An image collection unit(10) receives a video image. The image collection unit outputs a current frame image in the received video image to a prediction unit(20). The prediction unit predicts a 2D location of a face key point in the outputted current frame image. The prediction unit outputs the predicted 2D location as a face fitting unit(30). The face fitting unit obtains a 2D property and a 3D property of the face by fitting a predetermined face 2D model and a 3D model based on the predicted 2D location.
