APPARATUS FOR EXTRACTING FACIAL FEATURES TO IMPLEMENT REALISTIC INTERACTIVE SYSTEM AND METHOD THEREOF

摘要

According to an embodiment of the present invention, an image acquiring unit acquiring an image including a face; A face region detection unit detecting a face region from the image; A landmark detection unit detecting a plurality of landmarks representing the features of the face from the face region; A face direction estimator estimating the direction of the face from the plurality of landmarks; A pupil region detector which calculates a gradient vector from the brightness value of the image and detects a pupil region from the gradient vector; And calculating the dot product of the gradient vector and displacement vector to detect the pupil center in the pupil region, calculate a three-dimensional spherical coordinate from two-dimensional coordinates with respect to the pupil center, and obtain a three-dimensional rectangular coordinate from the three-dimensional spherical coordinates. It provides a face detection device including a; calculating, the pupil direction estimator for determining the three-dimensional rectangular coordinates in the pupil direction.
