Scene Graph Generation from Hierarchical Relationship Reasoning
share
This paper describes a novel approach to deducing relationships between objects in a visual scene. It explicitly exploits an informative hierarchical structure that can be imposed to divide the object and relationship categories into disjoint super-categories. Specifically, our proposed scheme implements a Bayes prediction head to jointly predict the super-category or type of relationship between the two objects, along with the detailed relationship within that super-category. This design reduces the impact of class imbalance problems. We present experimental results on the Visual Genome and OpenImage V6 datasets showing that this factorized approach allows a relatively simple model to achieve competitive performance, especially on predicate classification and zero-shot tasks.
