| Medium | GrooveSquid.com (original content) | Medium Difficulty Summary Recent advancements in text-to-image (T2I) diffusion models have enabled fine-grained spatial and appearance control through approaches like FreeControl and Diffusion Self-Guidance. However, these methods optimize latent embeddings for each type of score function with longer diffusion steps, making the generation process time-consuming and limiting flexibility. Ctrl-X, a simple framework, addresses this issue by designing feed-forward structure control to align structures with images and semantic-aware appearance transfer to facilitate user-input image-based appearance control. This paper presents extensive qualitative and quantitative experiments demonstrating Ctrl-X’s superior performance on various condition inputs and model checkpoints. Ctrl-X supports novel structure and appearance control with arbitrary condition images of any modality, exhibits better image quality and appearance transfer compared to existing works, and provides instant plug-and-play functionality to T2I and text-to-video (T2V) diffusion models. |
| Low | GrooveSquid.com (original content) | Low Difficulty Summary Imagine being able to create realistic images by telling a computer what you want it to look like. This paper introduces Ctrl-X, a new way to make this happen using “text-to-image” technology. The goal is to control the structure and appearance of an image based on text prompts or user-input images. Current methods can be slow and limited in their flexibility. Ctrl-X solves these problems by designing a simple framework that enables fine-grained control over image structure and appearance without requiring additional training or guidance. This allows for more realistic and customized image generation. The results are impressive, showing better performance on various tasks and the ability to generate images with different structures and appearances. |
