🤖 AI Summary
Existing artistic style transfer methods suffer from limited stylistic diversity and poor controllability. To address these limitations, we propose Artbank—a dynamic style prompting mechanism integrated with Stable Diffusion—to enable fine-grained, editable multi-style transfer. Our approach introduces (i) an extensible style prompt library (Artbank) coupled with CLIP-aligned, disentangled prompt routing for zero-shot style composition, continuous interpolation, and interactive control; and (ii) differentiable prompt optimization with dynamic style cache retrieval. Evaluated across 128 artistic styles, our method achieves 98.3% style fidelity, significantly outperforming StyleGAN- and ControlNet-based baselines in FID, LPIPS, and human evaluation metrics, while supporting real-time interactive editing.
