Joint Generative Modeling of Scene Graphs and Images via Diffusion Models

no code implementations2 Jan 2024 Bicheng Xu, Qi Yan, Renjie Liao, Lele Wang, Leonid Sigal

While previous works have explored image generation conditioned on scene graphs or layouts, our task is distinctive and important as it involves generating scene graphs themselves unconditionally from noise, enabling efficient and interpretable control for image generation.

Self-Supervised Relation Alignment for Scene Graph Generation

no code implementations2 Feb 2023 Bicheng Xu, Renjie Liao, Leonid Sigal

In the auxiliary branch, relational input features are partially masked prior to message passing and predicate prediction.

Consistent Multiple Sequence Decoding

no code implementations2 Apr 2020 Bicheng Xu, Leonid Sigal

Our formulation utilizes a consistency fusion mechanism, implemented using message passing in a Graph Neural Network (GNN), to aggregate context from related decoders.

Watch, Listen and Tell: Multi-modal Weakly Supervised Dense Event Captioning

no code implementations ICCV 2019 Tanzila Rahman, Bicheng Xu, Leonid Sigal

Multi-modal learning, particularly among imaging and linguistic modalities, has made amazing strides in many high-level fundamental visual understanding problems, ranging from language grounding to dense event captioning.
