APPARATUS AND METHOD FOR RECONSTRUCTING THREE-DIMENSIONAL FACE AVATAR THROUGH STEREO VISION AND FACE DETECTION
First Claim
1. An apparatus for reconstructing Three-Dimensional (3D) face avatar, comprising:
- a face detection unit receiving a left image and right image of a user, and detecting a face image of the user from the left and right images using a face detection algorithm;
a stereo matching unit receiving the left and right images of the user, and creating a depth map image from the left and right images through a stereo matching operation which uses disparity between the left and right images;
a bilateral filter abstracting the detected face image through a bilateral filtering operation; and
a texture mapping unit texture-mapping the abstracted face image on the created depth map image to reconstruct a 3D avatar.

Abstract
Provided are an apparatus and method for reconstructing 3D face avatar. The apparatus includes a face detection unit, a stereo matching unit, a bilateral filter, and a texture mapping unit. The face detection unit receives a left image and right image of a user, and detects a face image of the user from the left and right images using a face detection algorithm. The stereo matching unit receives the left and right images of the user, and creates a depth map image from the left and right images through a stereo matching operation which uses disparity between the left and right images. The bilateral filter abstracts the detected face image through a bilateral filtering operation. The texture mapping unit texture-maps the abstracted face image on the created depth map image to reconstruct a 3D avatar.
