Relational Proxies: Emergent Relationships as Fine-Grained Discriminators. (arXiv:2210.02149v1 [cs.CV])

Fine-grained categories that largely share the same set of parts cannot be
discriminated based on part information alone, as they mostly differ in the way
the local parts relate to the overall global structure of the object. We
propose Relational Proxies, a novel approach that leverages the relational
information between the global and local views of an object for encoding its
semantic label. Starting with a rigorous formalization of the notion of
distinguishability between fine-grained categories, we prove the necessary …
