Interactive Geometric Refinement of AI-Generated Images with Consistent Vanishing Points

Abstract (in Japanese) (See Japanese page) 
(in English) Recent text-to-image models have achieved impressive visual quality, yet they often suffer from geometric inconsistencies that undermine the structural realism of generated scenes. One prominent issue is vanishing point inconsistency, where projections of parallel lines fail to converge correctly in the 2D space. This leads to structurally implausible geometry degrading spatial realism, especially in architectural scenes. We propose a user-guided framework for correcting vanishing point inconsistencies in generated images. Our approach extends a pre-trained diffusion model by incorporating structural guidance based on building contours. We also introduce geometric constraints that explicitly encourage alignment between image edges and vanishing point directions. Our method enhances global geometric consistency while maintaining visual fidelity comparable to the baselines.
