Sequence Matters: Harnessing Video Models in 3D Super-Resolution

AAAI 2025technical

3D super-resolution aims to reconstruct high-fidelity 3D models from low-resolution (LR) multi-view images. Early studies primarily focused on single-image super-resolution (SISR) models to upsample LR images into high-resolution images. However, these methods often lack view consistency because the…

Masked Wavelet Representation for Compact Neural Radiance Fields

CVPR 2023poster

Neural radiance fields (NeRF) have demonstrated the potential of coordinate-based neural representation (neural fields or implicit neural representation) in neural rendering. However, using a multi-layer perceptron (MLP) to represent a 3D scene or object requires enormous computational resources and…

PIXEL: Physics-Informed Cell Representations for Fast and Accurate PDE Solvers

AAAI 2023technical

With the increases in computational power and advances in machine learning, data-driven learning-based methods have gained significant attention in solving PDEs. Physics-informed neural networks (PINNs) have recently emerged and succeeded in various forward and inverse PDE problems thanks to their e…
