UGOD: Uncertainty-Guided Differentiable Opacity and Soft Dropout for Enhanced Sparse-View 3DGS
Zhihao Guo, Peng Wang, Zidong Chen +4
3D Gaussian Splatting (3DGS) has become a competitive approach for novel view synthesis (NVS) due to its advanced rendering efficiency through 3D Gaussian projection and blending.…
A Spatial Relationship Aware Dataset for Robotics
Peng Wang, Minh Huy Pham, Zhihao Guo +1
Robotic task planning in real-world environments requires not only object recognition but also a nuanced understanding of spatial relationships between objects. We present a spatia…
GP-GS: Gaussian Processes Densification for 3D Gaussian Splatting
Zhihao Guo, Jingxuan Su, Chenghao Qian +8
3D Gaussian Splatting (3DGS) enables photorealistic rendering but suffers from artefacts due to sparse Structure-from-Motion (SfM) initialisation. To address this limitation, we pr…
Robot Shape and Location Retention in Video Generation Using Diffusion Models
Peng Wang, Zhihao Guo, Abdul Latheef Sait +1
Diffusion models have marked a significant milestone in the enhancement of image and video generation technologies. However, generating videos that precisely retain the shape and l…
LLM Granularity for On-the-Fly Robot Control
Peng Wang, Mattia Robbiani, Zhihao Guo
Assistive robots have attracted significant attention due to their potential to enhance the quality of life for vulnerable individuals like the elderly. The convergence of computer…
Depth Priors in Removal Neural Radiance Fields
Zhihao Guo, Peng Wang
Neural Radiance Fields (NeRF) have achieved impressive results in 3D reconstruction and novel view generation. A significant challenge within NeRF involves editing reconstructed 3D…
