Facial Expression and Gesture Low-Dimensional Analysis
Qiang Qiao · 2010
Facial expression and gesture change subtly, which is not robust to the noise. In the paper local linear embedded analysis is carried on facial gesture and expressions: in low-dimensional space, the gesture and expression distribution will not change with different faces. From left to right it reflects facial gesture change and from top to bottom it reflects facial expression change. The expression distribution does on change with image zoom and rotation.
