• Abstract: Controllable image generation has always been one of the core demands in image generation, aiming to create images that are both creative and logical while satisfying additional specified conditions. In the post-AIGC era, controllable generation relies on diffusion models and is accomplished by maintaining certain components or introducing inference interferences. This paper addresses key challenges in controllable generation: 1. mismatched object attributes during generation and poor prompt-following effects; 2. inadequate completion of controllable layouts. We propose a train-free method based on attention loss backward, cleverly controlling the cross attention map. By utilizing external conditions such as prompts that can reasonably map onto the attention map, we can control image generation without any training or fine-tuning. This method addresses issues like attribute mismatch and poor prompt-following while introducing explicit layout constraints for controllable image generation. Our approach has achieved excellent practical applications in production, and we hope it can serve as an inspiring technical report in this field.

  Recent text-to-image diffusion models excel at generating high-resolution images from text but struggle with precise control over spatial composition and object counting. We propose a novel zero-shot L2I approach, BACON, which eliminates the need for additional modules or fine-tuning. We leverage pixel-to-pixel correlations in the self-attention feature maps to align cross-attention maps and combine three loss functions constrained by boundary attention to update latent features.

  We introduce two innovative solutions for conditional text-to-image models. Firstly, we propose a Spatial Guidance (SGI) which enhances conditional detail by encoding text inputs with precise annotation information. Secondly, to overcome the issue of limited conditional supervision, we introduce Diffusion Consistency Loss. This encourages consistency between the latent code at each time step and the input signal, thereby enhancing the robustness and accuracy of the output.

Unlike existing methods, OFT can provably preserve hyperspherical energy which characterizes the pairwise neuron relationship on the unit hypersphere. We empirically show that our OFT framework outperforms existing methods in generation quality and convergence speed.
