Abstract

Variation of Facial expression is one of the most challenging factors in face recognition which significantly degrades the performance of the face recognition system. This paper presents a mechanism for reducing the high false positive rate in face recognition due to facial expression by using a novel Gaussian blurring and decimation algorithms. Extensive experimentation on complex images with variant facial expressions from the ORL dataset shows that removing the higher frequencies in the pre-processing step enhances the performance of eigenfaces algorithm by a significant amount i.e. from 93.75% to 96.5%.
