A Comprehensive Survey of Text Encoders for Text-to-Image Diffusion Models

In this comprehensive survey, we delve into the realm of text encoders for text-to-image diffusion models, focusing on the principles, challenges, and opportunities associated with these encoders. We explore the state-of-the-art models, including BERT, T5-XXL, and CLIP, that have revolutionized the way we approach language understanding and cross-modal interactions. These models, with their unique architectures and training techniques, enable remarkable capabilities in generating images from textual descriptions. However, they also face limitations and challenges, such as computational complexity and data scarcity. We discuss these issues and highlight potential opportunities for further research. By providing a comprehensive overview, this survey aims to contribute to the ongoing development of text-to-image diffusion models, enabling more accurate and efficient image generation from textual inputs.
