High-Quality Spatial Reconstruction and Orthoimage Generation Using Efficient 2D Gaussian Splatting
Qian Wang, Zhihao Zhan, Jialei He +2
Highly accurate geometric precision and dense image features characterize True Digital Orthophoto Maps (TDOMs), which are in great demand for applications such as urban planning, i…
Rethinking Video Super-Resolution: Towards Diffusion-Based Methods without Motion Alignment
Zhihao Zhan, Wang Pang, Xiang Zhu +1
In this work, we rethink the approach to video super-resolution by introducing a method based on the Diffusion Posterior Sampling framework, combined with an unconditional video di…
A Multi-Sensor Fusion Approach for Rapid Orthoimage Generation in Large-Scale UAV Mapping
Jialei He, Zhihao Zhan, Zhituo Tu +2
Rapid generation of large-scale orthoimages from Unmanned Aerial Vehicles (UAVs) has been a long-standing focus of research in the field of aerial mapping. A multi-sensor UAV syste…
Image Motion Blur Removal in the Temporal Dimension with Video Diffusion Models
Wang Pang, Zhihao Zhan, Xiang Zhu +1
Most motion deblurring algorithms rely on spatial-domain convolution models, which struggle with the complex, non-linear blur arising from camera shake and object motion. In contra…
