Abstract: In this paper, a fast and efficient gender and age estimation system based on facial images is developed. There are
many methods have been proposed in the literature for the age estimation and gender classification. However, all of them
have still disadvantage such as not complete reflection about face structure, face texture. This technique applies to both face
alignment and recognition and significantly improves three aspects. First, we introduce shape description for face model.
Second, the feature extraction phase, two geometric features are evaluated as the ratios of the distances between eyes, noses,
and mouths. Finally, we classified the gender and age based on the association of two methods: geometric feature based
method and Principal Component Analysis (PCA) method for improving the efficiency of facial feature extraction stage. The
face database contains the 13 individual groups. Within a given database, all weight vectors of the persons within the same
age group are averaged together. A range of an age estimation result is 15 to 70 years old, and divided into 13 classes with 5
years old range. Experimental results show that better gender classification and age estimation.
Keywords: gender classification, age estimation, principal component analysis, face recognition, feature extraction.
