This paper presents a gender classification method using LUT-based sub-images and DIE (Difference Image Entropy). The proposed method consists of three major steps; extraction of facial sub-images, construction of a LUT (Look-Up table), and calculation of DIE. Firstly, extraction of sub-images of the face, right eye, and mouth from face images is conducted using Haar-like features and AdaBoost proposed by Viola and Jones. Secondly, sub-images are converted using LUT. LUT-based sub-regions are constructed by calculation of one pixel and near pixels. Finally, sub-images are classified male or female using DIE. The DIE value is computed with histogram levels of a grayscale difference image which has peak positions from -255 to +255, to prevent information sweeping. The performance evaluation is conducted using five standard databases, i.e., PAL, BioID, FERET, PIC, and Caltech facial databases. The experimental results show good performance in comparison with earlier methods.
