1. Introduction
Portrait Quality Assessment (PQA) is becoming increasingly important in a variety of fields, from social media engagement to professional photography. The subjective nature of aesthetic appreciation, combined with the technical complexities of image capture and processing, makes PQA a challenging task. While Redi et al. [25] have explored the attributes that contribute to the perceived beauty of portraits, the utility-focused approach of Face Image Quality Assessment (FIQA) [27] underscores the diversity of criteria required for different quality assessment contexts.
