摘要
The present invention relates to a model-independent face landmark recognition apparatus in a spatial augmented reality. According to another aspect of the present invention, there is provided an image processing apparatus including: an image acquiring unit acquiring a face image including a color image and a depth image; A local binary pattern is calculated in the color image, a local angular pattern is calculated in the depth image, and the facial feature of the face image combined with the local previous pattern and the local angular pattern is calculated by detecting the face region in the face image acquired by the image acquiring unit, A facial feature detector for calculating a facial feature; And forming a face topology tree, which is a face phase relation tree, by dividing the set of upper face landmarks into two sets of lower faces, learning with a plurality of test face images including all face landmarks matching the root node of the face topology tree Learning is performed so that each node of the potential regenerative forest has a partial landmark image including a partial landmark subset along the face topology tree and the face feature of the face image detected by the face feature detector is used as an input value And a landmark detection unit for calculating a result of the partial landmark by traversing the learned forest and accumulating the difference of the position value stored in the division node and the leaf node in the spatial augmented reality, Is provided.
