OcclusionFormer tackles image generation occlusion with new framework

By PulseAugur Editorial · [2 sources] ·

Researchers have developed OcclusionFormer, a new framework designed to improve layout-grounded image generation by explicitly handling inter-object occlusion. Existing models struggle when bounding boxes overlap, leading to ambiguous or inconsistent layering. OcclusionFormer addresses this by using a novel Diffusion Transformer that models Z-order priority and employs volume rendering for compositing. The approach is supported by a new dataset, SA-Z, which includes explicit occlusion ordering and pixel-level annotations, leading to enhanced semantic consistency and accuracy in generated images.

    OcclusionFormer: Arranging Z-Order for Layout-Grounded Image Generation

    Recent layout-to-image models have achieved remarkable progress in spatial controllability. However, they still struggle with inter-object occlusion. When bounding boxes overlap, most existing methods lack explicit occlusion information, which makes the generation in intersection…
