2017 2017 International Conference on 3D Vision (3DV)  
Our method first selects a 3D model from a graph structure by using a novel free-form deformation FFD 3D-2D registration, and then the selected 3D model is refined to best fit the image silhouette.  ...  3D reconstruction from 2D images is a central problem in computer vision. Recent works have been focusing on reconstruction directly from a single image.  ...  We showed that dense 3D reconstruction from a single image can be performed using our compact model representation given the 2D anchors and the object silhouette.  ...
