Compositional Transformers for Scene Generation Supplementary Material

Figure 10: A visualization of the layouts and unsupervised depth maps produced by GANformer2's planning stage while synthesizing varied images, making the generative process more structured and interpretable. GANformer2 creates the layout sequentially, segment-by-segment, to capture the scene's compositionality, effectively allowing us to add or remove objects from the resulting images. Since GANformer2 creates each scene as a composition of interacting segments, it supports adding and removal of objects while respecting various dependencies with their surroundings: Amodal completion of occluded objects is denoted by pink, updates of shadows and especially reflections by cyan, and other object removals cases by yellow. Shape manipulation is denoted by green, while position changes by yellow. Color manipulation is denoted by pink, while updates of material by cyan.
