A Hierarchical Graph-based Approach for Recognition and Description Generation of Bimanual Actions in Videos

no code implementations1 Oct 2023 Fatemeh Ziaeetabar, Reza Safabakhsh, Saeedeh Momtazi, Minija Tamosiunaite, Florentin Wörgötter

To achieve this, we encode, first, the spatio-temporal inter dependencies between objects and actions with scene graphs and we combine this, in a second step, with a novel 3-level architecture creating a hierarchical attention mechanism using Graph Attention Networks (GATs).
