Due to changes in the reality are linear physics position changes while in the image space are nonlinear, thus head pose has great influence for facial feature detection. In this paper, it proposes a precision head pose estimation method as a condition of regression forests, the algorithm modifies the performance of the nonlinear problem into a linear one.The main idea is used by Locality Preserving Projection and Nonlinear Regression(LPP + NLR)for obtaining the global information of pose and label, then, i...
