Automatic localization of facial key-points for 3D face modeling
Guanghua Gu · Journal of Computer Applications · 2010
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.
