Abstract: In view of the key-points acquirement problem in morphable way of 3D face modeling, an automatic localization method was proposed. First of all, according to the demand, the locations of key-points were determined and classified. Secondly, by using the S component in HIS color space, the head was detected. Thirdly, combined with the structure of face features and texture, the features' parts were extracted. Then, using different methods, the 2D coordinates of the different key-points were gained at the features' parts from frontal and side photos respectively. Finally, merging the 2D coordinates from both views, the 3D coordinates of the key-points were obtained. The experimental results show that the proposed method has good performance in speed and accuracy.
