Comprehensive Relation Modelling for Image Paragraph Generation

  • Image paragraph generation aims to generate a long description composed of multiple sentences, which is different from traditional image captioning containing only one sentence. Most of previous methods are dedicated to extracting rich features from image regions, and ignore modelling the visual relationships. In this paper, we propose a novel method to generate a paragraph by modelling visual relationships comprehensively. First, we parse an image into a scene graph, where each node represents a specific object and each edge denotes the relationship between two objects. Second, we enrich the object features by implicitly encoding visual relationships through a graph convolutional network (GCN). We further explore high-order relations between different relation features using another graph convolutional network. In addition, we obtain the linguistic features by projecting the predicted object labels and their relationships into a semantic embedding space. With these features, we present an attention-based topic generation network to select relevant features and produce a set of topic vectors, which are then utilized to generate multiple sentences. We evaluate the proposed method on the Stanford image-paragraph dataset which is currently the only available dataset for image paragraph generation, and our method achieves competitive performance in comparison with other state-of-the-art (SOTA) methods.
