I am thrilled to share the exciting news that our paper, titled “Ref-NeuS: Ambiguity-Reduced Neural Implicit Surface Learning for Multi-View Reconstruction with Reflection,” has been nominated for the Best Paper Award at the prestigious ICCV 2023 conference. This nomination is a testament to the hard work and innovative research conducted by our team. Below is a brief overview of our paper and its contributions.
Overview
Abstract
Neural implicit surface learning has shown significant progress in multi-view 3D reconstruction, where an object is represented by multilayer perceptrons providing continuous implicit surface representation and view-dependent radiance. However, existing methods struggle to accurately reconstruct reflective surfaces, leading to severe ambiguity. Our proposed model, Ref-NeuS, addresses this issue by attenuating the importance of reflective surfaces through a novel approach.
Introduction
3D reconstruction is essential in computer vision, serving as the foundation for fields like computer-aided design, animation, and virtual reality. Image-based 3D reconstruction, which recovers 3D structures from 2D images, is particularly challenging. Traditional methods often require cumbersome multi-step pipelines. Our approach leverages neural implicit surface learning for end-to-end and unsupervised training, achieving high-quality reconstruction even on reflective surfaces.
Key Contributions
- Reflection-Aware Photometric Loss: We introduce a reflection-aware photometric loss that reduces the influence of reflective surfaces. This is achieved by modeling the rendered color as a Gaussian distribution, where the reflection score represents the variance.
- Reflection Score Estimation: We utilize an anomaly detector to estimate an explicit reflection score with multi-view context guidance to localize reflective surfaces accurately.
- High-Quality Surface Reconstruction: Our model significantly outperforms state-of-the-art methods in reconstructing reflective surfaces, providing more accurate surface geometry, normals, and rendering realism.
Results
Our extensive experiments demonstrate that Ref-NeuS achieves high-quality surface reconstruction on reflective surfaces, outperforming other methods by a large margin. The model is also competitive on general surfaces, showing its robustness and versatility.
Conclusion
Being nominated for the Best Paper Award at ICCV 2023 is a great honor for our team. It acknowledges our efforts to advance the field of 3D reconstruction with innovative solutions that address long-standing challenges. We look forward to presenting our work at the conference and engaging with the community to further this exciting research.
