DogRecon: Canine Prior-Guided Animatable 3D Gaussian Dog Reconstruction From A Single Image
摘要
We tackle animatable 3D dog reconstruction from a single image, noting the overlooked potential of animals. Particularly, we focus on dogs, emphasizing their intrinsic characteristics that complicate 3D observation. First, the considerable variation in shapes across breeds presents a complexity for modeling. Additionally, the nature of quadrupeds leads to frequent joint occlusions compared to humans. These challenges make 3D reconstruction from 2D observations difficult, and it becomes dramatically harder when constrained to a single image. To address these challenges, our insight is to combine the acquisition of appearance from generative models, without additional data, with geometric guidance provided by a parametric representation, aiming to achieve complete geometry. To this end, we present
