摘要(Abstract)：

The histogram of oriented gradient has been successfully applied in many research fields with excellent performance especially in pedestrian detection.However,the method has rarely been applied to face recognition.Aimed to develop a fast and efficient new feature for face recognition,the original HOG and its variations were applied to evaluate the effects of different factors.An information theory-based criterion was also developed to evaluate the potential classification power of different features.Comparative experiments show that even with a relatively simple feature descriptor,the proposed HOG feature achieves almost the same recognition rate with much lower computational time than the widely used Gabor feature on the FRGC and CAS-PEAL databases.
