报告题目:3D from Single Images using a Large-scale Shape Repository

主持人:任传贤(中山大学)


报告摘要:

Recent technological developments have led to an explosion in the amount of 3D data. With this background, we build a knowledge-base that stores rich information on top of networks of 3D models. Knowledge stored on ShapeNet can be used as priors of geometry and physics attributes for understanding contents of RGB(D) images.

We believe that such a 3D-centric knowledge-base, named ShapeNet, is beneficial to many aspects of our life, since we live in a world where 3D is the natural space. We jointly analyze 3D models and 2D images for various applications. The key idea is to bridge CG and CV: we render ShapeNet models into large volume of images with free yet detailed annotation. With such synthetic data in the virtual environment, we train high capacity models such as CNN and adapt the learned models in real world scenarios. We show various applications that achieve state-of-the-art performance, such as single-image based 3D reconstruction, image-based shape retrieval, 3D viewpoint estimation, texture transfer from images to shapes, 3D human pose estimation, and novel view feature synthesis.
