A Practical Study on Quality Evaluation for Age Recognition Systems

Face recognition system is a widely-used intelligent application nowadays. Existing recognition system evaluation methods primarily focus on recognition rate, i.e., the correct result. However, current research seldom focuses on the quality evaluation of face recognition systems. They seldom consider accuracy or the quality of recognition. To address this issue, this paper proposes several quality factors for evaluation. In addition, corresponding metrics for diverse quality factors are illustrated. Moreover, the paper presents an experimental study on a realistic non-trial face age recognition system using the proposed quality evaluation method. The study result shows the proposed method is feasible and effectiveness in quality evaluation.
