➡️Paper Title: LookCloser 🔍: Frequency-aware Radiance Field for Tiny-Detail Scene
🌟Few pointers from the paper
🎯Humans perceive and comprehend their surroundings through information spanning multiple frequencies.
🎯In immersive scenes, people naturally scan their environment to grasp its overall structure while examining fine details of objects that capture their attention.
🎯However, current NeRF frameworks primarily focus on modeling either high-frequency local views or the broad structure of scenes with low-frequency information, which is limited to balancing both.
🎯Authors of this paper introduced “FA-NeRF”, a novel frequency-aware framework for view synthesis that simultaneously captures the overall scene structure and high-definition details within a single NeRF model.
🎯To achieve this, they proposed a 3D frequency quantification method that analyzes the scene’s frequency distribution, enabling frequency-aware rendering.
🎯Their framework incorporates a frequency grid for fast convergence and querying, a frequency-aware feature re-weighting strategy to balance features across different frequency contents.
🎯Extensive experiments show that their method significantly outperforms existing approaches in modeling entire scenes while preserving fine details.
