It plays a vital role in computer vision, specifically in crucial applications such as behaviour analysis, public safety monitoring, and video surveillance. However, existing PAR approaches are unable to achieve substantial performance due to multiple factors. First, multiple appearances of the same attribute confuse the models. Second, adverse weather and lighting conditions restrict model generalization capability. To mitigate these challenges, this paper proposes a new evaluation baseline that uses Vision Transformer (ViT) blocks for hierarchical feature modelling. The approach categorizes attributes into different spatial granularity levels and employs diverse patch formations to extract discriminative features. Furthermore, we introduce an enhanced loss function for stable training in the re-formulated granularity scenario, where a novel attribute-aware granularity factor influences the loss. The proposed baseline has been extensively evaluated on the three popular PAR datasets, namely RAP, PA100K and PETA.
