Image Restoration via Diffusion Models with Dynamic Resolution
Yang Zheng, Wen Li, Zhaoqiang Liu
Diffusion models (DMs) have exhibited remarkable efficacy in various image restoration tasks. However, existing approaches typically operate within the high-dimensional pixel space…
GeoQuery: Geometry-Query Diffusion for Sparse-View Reconstruction
Xiao Cao, Yuze Li, Youmin Zhang +4
3D Gaussian Splatting (3DGS) has emerged as a prominent paradigm for 3D reconstruction and novel view synthesis. However, it remains vulnerable to severe artifacts when trained und…
Outlier-Robust Diffusion Solvers for Inverse Problems
Yang Zheng, Jiahua Liu, Tongyao Pang +2
Methods based on diffusion models (DMs) for solving inverse problems (IPs) have recently achieved remarkable performance. However, DM-based methods typically struggle against outli…
FastAvatar: Towards Unified and Fast 3D Avatar Reconstruction with Large Gaussian Reconstruction Transformers
Yue Wu, Xuanhong Chen, Yufan Wu +3
Despite significant progress in 3D avatar reconstruction, it still faces challenges such as high time complexity, sensitivity to data quality, and low data utilization. We propose…
