Generating Contextual Images for Long-Form Text

Abstract

We investigate the problem of synthesizing relevant visual imagery from generic long-form text, leveraging Large Language Models (LLMs) and Text-to-Image Models (TIMs). Current Text-to-Image models require short prompts that describe the image content and style explicitly. Unlike image prompts, generation of images from general long-form text requires the image synthesis system to derive the visual content and style elements from the text. In this paper, we study zero-shot prompting and supervised fine-tuning approaches that use LLMs and TIMs jointly for synthesizing images. We present an empirical study on generating images for Wikipedia articles covering a broad spectrum of topic and image styles. We compare these systems using a suite of metrics, including a novel metric specifically designed to evaluate the semantic correctness of generated images. Our study offers a preliminary understanding of existing models’ strengths and limitation for the task of image generation from long-form text, and sets up an evaluation framework and establishes baselines for future research.
