CS Colloquium: Vitomir Struc (University of Ljubljana)
Title: Face Image Quality Assessment (FIQA): Recent Advancements and Future Challenges
Abstract: Understanding the quality characteristics of facial images is of key importance for various face-related applications, ranging from biometric verification systems and problems in surveillance and security to applications in human-machine interaction and affective computing. In this talk, I will first talk about the general problem of Face Image Quality Assessment (FIQA) and discuss how it differs from the more perceptually driven Image Quality Assessment (IQA) task that is used for quality assessment of arbitrary natural images. I will then elaborate on the most interesting trends and solutions towards face image quality assessment and present two of our recent models for this task, i.e., (i) FaceQAN that predicts quality based on the analysis of adversarial noise, and (ii) DifFIQA that uses probabilistic denoising diffusion models to estimate face image quality. Finally, I will share some insights with respect to FIQA techniques and highlight some open issues and future research directions in this space.
