Clifford Algebra Approach for 3D Face Pose Correction
Hua Liang · Journal of Chinese Computer Systems · 2013
The 3D face samples within no-front plane would influence the feature extraction and recognition of them,therefore it should be pose corrected in the preprocessing state to be within the front plane.This paper proposed a method for 3D face pose correction based on Clifford algebra,namely,fixed on the frontal plane of 3D face by computing and detecting some specific points on it;and then constructed Clifford geometrical rotator for vertexes coordinate to rotate for the purpose of 3D face pose correction.The experimental results indicated that the proposed method made the calculation easy,and had clearly geometrical meaning and high accuracy of correction,it can be widely application.
