• Abstract summary: Previous work focused on classifying figure content rather than understanding how images relate to the text. MedICaT consists of 217K images from 131K open access biomedical papers. Using MedICaT, we introduce the task of subfigure to subcaption alignment in compound figures.

• Abstract: Understanding the relationship between figures and text is key to scientific document understanding. Medical figures in particular are quite complex, often consisting of several subfigures (75% of figures in our dataset), with detailed text describing their content. Previous work studying figures in scientific papers focused on classifying figure content rather than understanding how images relate to the text. To address challenges in figure retrieval and figure-to-text alignment, we introduce MedICaT, a dataset of medical images in context. MedICaT consists of 217K images from 131K open access biomedical papers, and includes captions, inline references for 74% of figures, and manually annotated subfigures and subcaptions for a subset of figures. Using MedICaT, we introduce the task of subfigure to subcaption alignment in compound figures and demonstrate the utility of inline references in image-text matching.

  Existing contrastive language-image pre-training aims to learn a joint representation by matching abundant image-text pairs. We propose a Medical Language-Image Pre-training framework, which exploits the limited image-text medical data more efficiently. Our evaluation results show that MLIP outperforms previous work in zero/few-shot classification and few-shot segmentation tasks by a large margin.

  We build on the concept of image manifold to represent the feature space of images, learned via neural networks, as a graph. We augment the manifold samples with geometrically aligned text, thereby using a plethora of sentences to teach us about images. The experimental results show that the joint embedding manifold is a robust representation, allowing it to be a better basis to perform image retrieval.

  This paper focuses on leveraging multi-modal content in the form of visual and textual cues to tackle the task of fine-grained image classification and retrieval. We employ a Graph Convolutional Network to perform multi-modal reasoning and obtain relationship-enhanced features by learning a common semantic space between salient objects and text found in an image.

  Text is omnipresent in human environments and frequently critical to understand our surroundings. To study how to comprehend text in the context of an image we collect a novel dataset, TextCaps, with 145k captions for 28k images. Our dataset challenges a model to recognize text, relate it to its visual context, and decide what part of the text to copy or paraphrase.
