Controllable Generation with Text-to-Image Diffusion Models: A Comprehensive Survey

Q: How can training-free methods enhance personalization in text-to-image diffusion models?

Training-free methods can enhance personalization in text-to-image diffusion models by leveraging external references or knowledge to steer the generative process without the need for extensive training. These methods typically extract concept information from reference images during the synthesis process, allowing the model to faithfully generate given concepts. By incorporating knowledge from samples, training-free methods can ensure that the generated images align closely with specific conditions or styles provided by these references. This approach not only streamlines the customization process but also helps maintain a high level of fidelity and relevance in the generated outputs.

Q: What are the implications of decoupling concept guidance and control guidance in distribution-driven generation?

Decoupling concept guidance and control guidance in distribution-driven generation has significant implications for generating diverse results reflective of a particular data distribution. By separating these two components, one focused on steering the sampling process based on underlying data distribution (concept guidance) and another controlling how this sampling is carried out (control guidance), models can achieve more accurate and varied outputs within a given category or concept. This separation allows for better fine-tuning of each aspect independently, leading to improved accuracy in generating results that align with specific distributions while maintaining flexibility and editability.

Q: How can spatial signals like layout and human pose be effectively integrated into text-to-image diffusion models?

Integrating spatial signals like layout and human pose into text-to-image diffusion models involves developing mechanisms to incorporate these structural elements effectively during image generation. One approach is through spatial-conditional score prediction, where methods are designed to model how spatial conditions influence image synthesis alongside textual prompts. Techniques such as bounding boxes, keypoints, human parsing, segmentation masks, among others are utilized to provide detailed structure information guiding the generative process accurately. By incorporating these spatial signals into diffusion models through specialized encoders or attention mechanisms tailored for layout or pose information extraction ensures that generated images adhere closely to specified structural requirements while maintaining high quality output across various applications requiring precise spatial control.
