ID-Sim: An Identity-Focused Similarity Metric
arXiv:2604.05039v1 Announce Type: new Abstract: Humans have remarkable selective sensitivity to identities — easily distinguishing between highly similar identities, even across significantly different contexts such as diverse viewpoints or lighting. Vision models have struggled to match this capability, and progress toward identity-focused tasks such as personalized image generation is slowed by a lack of identity-focused evaluation metrics. To help facilitate progress, we propose ID-Sim, a feed-forward metric designed to faithfully reflect human selective sensitivity. To build ID-Sim, we […]
