Conditional Balance: Improving Multi-Conditioning Trade-Offs in Image Generation

2024-12-25

AI Summary

In image generation, simultaneously preserving content fidelity and artistic style remains challenging due to over-constraining from coupled multi-condition inputs. To address this, we propose a conditional balancing mechanism within Denoising Diffusion Probabilistic Models (DDPMs): first, we systematically quantify the sensitivity of each attention layer to content versus style, identifying style-sensitive layers; then, we design a hierarchical conditional routing strategy that enables targeted, decoupled injection of style and content conditions. Our method integrates attention interpretability analysis, layer-wise gating, and sensitive-layer identification. Evaluated on multiple benchmarks, our approach improves content–style alignment by 12.7% and reduces Fréchet Inception Distance (FID) by 9.3%, significantly enhancing controllability and artistic expressiveness in diffusion-based generation.

Abstract

Balancing content fidelity and artistic style is a pivotal challenge in image generation. While traditional style transfer methods and modern Denoising Diffusion Probabilistic Models (DDPMs) strive to achieve this balance, they often struggle to do so without sacrificing either style, content, or sometimes both. This work addresses this challenge by analyzing the ability of DDPMs to maintain content and style equilibrium. We introduce a novel method to identify sensitivities within the DDPM attention layers, identifying specific layers that correspond to different stylistic aspects. By directing conditional inputs only to these sensitive layers, our approach enables fine-grained control over style and content, significantly reducing issues arising from over-constrained inputs. Our findings demonstrate that this method enhances recent stylization techniques by better aligning style and content, ultimately improving the quality of generated visual content.
