Facial feature descriptor using hybrid projection entropy in multi-scale transform domain
Jianping Li · Computer Engineering and Applications Journal · 2011
This paper proposes a new facial image feature description method.This method uses the Contourlet transform to get the low frequency sub-band and divides the sub-band image into several appropriate non-overlapping blocks so that the local image distortion will less affect the recognition result.It uses the hybrid projection function and image entropy to extract the features and construct the hybrid projection feature vector.The experimental results on ORL,Yale and CMU PIE face databases demonstrate that the new method is competitive.
