Abstract

This paper presents a novel Gabor-based Kernel Fisher Discriminant Analysis (KFDA) method to determine human pose under depth rotation (out of the image plane) Specially, the capability of different orientation and size of Gabor Filter is discussed and the optimal one is selected for feature representation Then KFDA with fractional power polynomial models leads to a non-linear projection to meet the non-linear depth rotation of human face In the experiment section, we can see that, the correct classification rate of 93.5% is achieved in MIT database.
