<ul><li>Pro-DG is a framework for procedurally controllable photo-realistic facade generation that combines a procedural shape grammar with diffusion-based image synthesis.</li><li>The framework reconstructs the facade layout from a single input image and allows user-defined transformations to edit the structure.</li><li>A hierarchical matching procedure aligns facade structures at different levels and control maps guide a generative diffusion pipeline, enabling large-scale edits while preserving local appearance fidelity.</li><li>Pro-DG outperforms inpainting-based baselines and synthetic ground truths in terms of preservation of architectural identity and edit accuracy.</li></ul>
