多视角级联回归模型人脸特征点定位
Multi-View and Cascaded Regression Model for Face Alignment
摘要
Abstract
Aiming at the problem of low precision when locating facial landmarks due to large pose variations in face images, a multi-view face alignment algorithm is proposed. Cascaded Pose Regression(CPR)model is used to establish many different models under multi-view face images, which combines local learning principle with random forest and global linear regression. Multi-view models are established to improve face alignment accuracy, replacing a single model. Firstly, CPR model is used to establish different models for multi-view face images. Then, multi-view generative model is used to estimate the face pose of an input face image. Finally, according to face pose, a corresponding model is selected for an input image, which achieves high precision for face alignment. The experimental results show that the proposed face alignment algorithm has higher location precision than several existing face alignment algorithms.关键词
