Predicting Gender and Race from Near Infrared Iris and Periocular Images

by   Denton Bobeldyk, et al.

Recent research has explored the possibility of automatically deducing information such as gender, age and race of an individual from their biometric data. While the face modality has been extensively studied in this regard, relatively less research has been conducted in the context of the iris modality. In this paper, we first review the medical literature to establish a biological basis for extracting gender and race cues from the iris. Then, we demonstrate that it is possible to use simple texture descriptors, like BSIF (Binarized Statistical Image Feature) and LBP (Local Binary Patterns), to extract gender and race attributes from a NIR ocular image used in a typical iris recognition system. The proposed method predicts race and gender with an accuracy of 86 prediction algorithms. In addition, the following analysis are conducted: (a) the role of different parts of the ocular region on attribute prediction; (b) the influence of gender on race prediction, and vice-versa; (c) the generalizability of the method across different datasets, i.e., cross-dataset performance; and (d) the consistency of prediction performance across the left and right eyes.
