• Abstract: Recent 3D novel view synthesis (NVS) methods are limited to single-object-centric scenes and struggle with complex environments. They often require extensive 3D data for training, lacking generalization beyond the training distribution. Conversely, 3D-free methods can generate text-controlled views of complex, in-the-wild scenes using a pretrained stable diffusion model without the need for a large amount of 3D-based training data, but lack camera control. In this paper, we introduce a method capable of generating camera-controlled viewpoints from a single input image, by combining the benefits of 3D-free and 3D-based approaches. Our method excels in handling complex and diverse scenes without extensive training or additional 3D and multiview data. It leverages widely available pretrained NVS models for weak guidance, integrating this knowledge into a 3D-free view synthesis approach to achieve the desired results. Experimental results demonstrate that our method outperforms existing models in both qualitative and quantitative evaluations, providing high-fidelity and consistent novel view synthesis at desired camera angles across a wide variety of scenes.

  We propose WildFusion, a new approach to 3D-aware image synthesis based on latent diffusion models (LDMs) Our 3D-aware LDM is trained without any direct supervision from multiview images or 3D geometry. This opens up promising research avenues for scalable 3D-aware image synthesis and 3D content creation from in-the-wild image data.

  This paper targets on learning-based novel view synthesis from a single or limited 2D images without the pose supervision. We construct an end-to-end trainable conditional variational framework to disentangle the unsupervisely learned relative-pose/rotation and implicit global 3D representation. Our system can achieve implicitly 3D understanding without explicitly 3D reconstruction.
