Learning multi-view manifold for single image based modeling

Image based modeling has an inherent problem that the complete geometry and appearance of a 3D object cannot be directly acquired from limited 2D images, namely reconstruction of a 3D object when only sporadic views are available is challenging due to occlusions and ambiguities within limited views. In this paper, we present a generative network architecture to address the problem of single image based modeling by learning multi-view manifold of 3D objects, which we call Multi-view GAN. Penalties for shape identity consistency and view diversity are introduced to guide the learning process, and Multi view GAN can provide a powerful representation which consists of 3D descriptors both for shape and view. This disentangled and oriented representation affords us to explore the manifold of views, thus one can detail a 3D object without "blind spot" even if only single view is available. We have evaluated our method on multi-view and 3D shape generation with a wide range of examples, and both qualitative and quantitative results demonstrate that our Multi-view GAN significantly outperforms state-of-the-art methods.
