CIPS-3D++: End-to-End Real-Time High-Resolution 3D-Aware GANs for GAN Inversion and Stylization
Summary
CIPS-3D++ enhances 3D-aware Generative Adversarial Networks (GANs) for high-resolution image synthesis and editing. This robust and efficient model achieves state-of-the-art results, enabling precise control over camera poses and 3D reconstruction.
Area of Science:
- Computer Vision
- Artificial Intelligence
- Deep Learning
Background:
- Style-based Generative Adversarial Networks (GANs) excel at image generation but lack explicit control over camera poses.
- NeRF-based GANs offer progress in 3D-aware image generation but often suffer from rotational non-invariance and computational inefficiency.
- Existing methods struggle with robustness, image quality, and high computational costs, hindering practical applications.
Purpose of the Study:
- To develop a highly robust, high-resolution, and computationally efficient 3D-aware GAN.
- To enable precise control over camera poses and facilitate 3D-aware image editing and synthesis.
- To establish a versatile platform for advancing 3D-aware generative models.
Main Methods:
- Introduced CIPS-3D, a style-based GAN with a shallow NeRF-based 3D shape encoder and a deep MLP-based 2D image decoder for rotation-invariant generation.
- Developed CIPS-3D++, incorporating geometric regularization and upsampling for enhanced high-resolution image synthesis and editing efficiency.
- Implemented an auxiliary discriminator for the NeRF network to address mirror symmetry issues during training.
Main Results:
- CIPS-3D++ achieves state-of-the-art 3D-aware image synthesis, reaching an FID score of 3.2 on FFHQ at 1024x1024 resolution.
- The model demonstrates high computational efficiency with a low GPU memory footprint, allowing end-to-end training on high-resolution images.
- Introduced FlipInversion, a 3D-aware GAN inversion algorithm for single-view 3D object reconstruction and 3D-aware stylization.
Conclusions:
- CIPS-3D++ significantly advances 3D-aware GANs, offering unprecedented robustness, resolution, and efficiency.
- The model provides a powerful foundation for transferring 2D image editing techniques to the 3D domain.
- CIPS-3D++ facilitates novel applications including 3D reconstruction and stylization from single images.
