Can Image Quality Metrics Detect Face Liveness?

In this research paper, we delve into the impact of image quality metrics on face liveness detection. We conducted evaluations on eight distinct image quality metrics across four widely utilized face liveness detection databases. The experimental findings reveal that the chosen image quality metrics are initially unable to effectively differentiate between bona fide and spoofed face samples in their original state. Nevertheless, their performance demonstrates a significant improvement and becomes comparable to state-of-the-art traditional face liveness detection methods after fine-tuning them with liveness detection datasets.
