Abstract: Generating multiple images of an object from different viewpoints is useful to generate 3D objects. The present disclosure describes a text-to-multi-view diffusion model that produces dense and consistent multi-view images of an object, which can be used by 3D reconstruction algorithms to generate 3D objects. For enhanced efficiency, multi-view images are encoded in a spatio-temporally compressed latent space, significantly reducing latency in multi-view generation with a slight performance tradeoff. Effective training of the model was achieved by strategically decomposing training into a plurality of steps. The present systems and methods are believed to outperform existing text-to-multi-view generation methods, in both image quality and multi-view consistency, while benefiting from the efficiency gains of spatio-temporal latents.
