• Abstract summary: Scene graph generation (SGG) represents the relationships between objects in an image as a graph structure. Previous studies have failed to reflect the co-occurrence of objects during SGG generation. We propose CooK, which reflects the Co-occurrence Knowledge between objects, and the learnable term frequency-inverse document frequency.

• Abstract: Scene graph generation (SGG) is an important task in image understanding because it represents the relationships between objects in an image as a graph structure, making it possible to understand the semantic relationships between objects intuitively. Previous SGG studies used a message-passing neural networks (MPNN) to update features, which can effectively reflect information about surrounding objects. However, these studies have failed to reflect the co-occurrence of objects during SGG generation. In addition, they only addressed the long-tail problem of the training dataset from the perspectives of sampling and learning methods. To address these two problems, we propose CooK, which reflects the Co-occurrence Knowledge between objects, and the learnable term frequency-inverse document frequency (TF-l-IDF) to solve the long-tail problem. We applied the proposed model to the SGG benchmark dataset, and the results showed a performance improvement of up to 3.8% compared with existing state-of-the-art models in SGGen subtask. The proposed method exhibits generalization ability from the results obtained, showing uniform performance improvement for all MPNN models.

  Scene graph generation (SGG) captures the relationships between objects in an image and creates a structured graph-based representation. Existing SGG methods have a limited ability to accurately predict detailed relationships. A new approach to the modeling multiobject relationships, called edge dual scene graph generation (EdgeSGG), is proposed herein.

  Scene graph generation (SGG) is a fundamental task aimed at detecting visual relations between objects in an image.

Our method can support inference over completely unseen object classes, which existing methods are incapable of handling.

  Many scene graph generation (SGG) models solely use the limited annotated relation triples for training. We propose a novel semantic compositional learning strategy that makes it possible to construct additional, realistic relation triples. For three recent SGG models, adding our strategy improves their performance by close to 50%, and all of them substantially exceed the current state-of-the-art.

  A major challenge is that intrinsic similarities between foreground objects and background surroundings make the features extracted by deep model indistinguishable. We design a novel Mutual Graph Learning model, which generalizes the idea of conventional mutual learning from regular grids to the graph domain. In contrast to most mutual learning approaches that use a shared function to model all between-task interactions, MGL is equipped with typed functions for handling different complementary relations.
