Research of facial features extraction technology based on Trace transform
基于Trace变换的人脸特征提取技术研究*

This paper proposed a novel facial feature extraction scheme and a new way for facial representation, which couldimprove the ability to discriminate different persons’ face images while also recognize same person’ s face images with differentexpressions or under different lighting conditions. It combined several functions together to process the preprocessed originalface images, which would produce feature vectors of the original face images. Experimental results on ORL face database provethat the facial feature extracted by this scheme can discriminate different persons’ face images while also recognize the sameperson’ s different face images. Therefore, this algorithm is feasible in practical applications of face recognition.
