Core Concepts
RoGUENeRF enhances NeRF renderings by combining 3D alignment, non-rigid refinement, and geometric attention for improved image quality.
Abstract
RoGUENeRF introduces a novel approach to enhance NeRF renderings by addressing issues such as high-frequency detail reconstruction and inaccurate camera calibration. By combining 3D alignment, non-rigid refinement, and geometric attention, RoGUENeRF substantially improves the rendering quality over various NeRF baselines and existing enhancers. The method leverages nearby training images to restore high-frequency textures while maintaining geometric consistency. Through pre-training and fine-tuning strategies, RoGUENeRF achieves significant improvements in PSNR, SSIM, and LPIPS metrics across different datasets. The model demonstrates robustness to inaccurate camera calibration and can quickly adapt to new scenes with minimal fine-tuning time.
