The paper "Neural 3D Mesh Renderer" by Hiroharu Kato, Yoshitaka Ushiku, and Tatsuya Harada proposes a method to integrate 3D mesh rendering into neural networks, enabling backpropagation and training. The authors address the challenge of rasterization, a discrete operation that prevents backpropagation, by introducing an approximate gradient for rendering. This allows the integration of rendering into neural networks, facilitating end-to-end training.
The paper presents two main applications:
1. **Single-image 3D Mesh Reconstruction**: The system reconstructs 3D meshes from single images using silhouette supervision, outperforming existing voxel-based approaches in terms of visual appeal and accuracy.
2. **Gradient-based 3D Mesh Editing**: The system performs 3D mesh editing tasks, such as 2D-to-3D style transfer and 3D DeepDream, using 2D supervision for the first time.
The authors demonstrate the effectiveness of their method through experiments, showing that their mesh-based approach outperforms voxel-based methods in 10 out of 13 categories. They also provide qualitative and quantitative evaluations, highlighting the advantages of their method in terms of visual quality and reconstruction accuracy.
The paper concludes by discussing the potential of integrating mesh renderers into neural networks and the effectiveness of the proposed renderer, suggesting that it can be applied to a wide range of problems in 3D understanding and editing.The paper "Neural 3D Mesh Renderer" by Hiroharu Kato, Yoshitaka Ushiku, and Tatsuya Harada proposes a method to integrate 3D mesh rendering into neural networks, enabling backpropagation and training.
