Exo2EgoHOI: Hand-Object-Interaction Aware Exocentric-to-Egocentric Video Generation
Hongjia Zhai, Xiyu Zhang, Haoran Zhang +5
Egocentric videos of human manipulation provide valuable visual experience for embodied intelligence, yet collecting such data at scale is costly. Exocentric-to-egocentric video ge…
QuerySplat: Decoupling Geometry and Appearance Representations in 3DGS Prediction
Yinglong Li, Donghui Shen, Xiaoyu Zhang +5
While feed-forward 3D Gaussian Splatting (3DGS) enables efficient 3D reconstruction, achieving high-fidelity rendering remains challenging. Existing pixel-aligned approaches suffer…
INSPATIO-WORLD: A Real-Time 4D World Simulator via Spatiotemporal Autoregressive Modeling
InSpatio Team, Donghui Shen, Guofeng Zhang +20
Building world models with spatial consistency and real-time interactivity remains a fundamental challenge in computer vision. Current video generation paradigms often struggle wit…
SparseCam4D: Spatio-Temporally Consistent 4D Reconstruction from Sparse Cameras
Weihong Pan, Xiaoyu Zhang, Zhuang Zhang +4
High-quality 4D reconstruction enables photorealistic and immersive rendering of the dynamic real world. However, unlike static scenes that can be fully captured with a single came…
InSpatio-WorldFM: An Open-Source Real-Time Generative Frame Model
InSpatio Team, Donghui Shen, Guofeng Zhang +16
We present InSpatio-WorldFM, an open-source real-time frame model for spatial intelligence. Unlike video-based world models that rely on sequential frame generation and incur subst…
PostCam: Camera-Controllable Novel-View Video Generation with Query-Shared Cross-Attention
Yipeng Chen, Zhichao Ye, Zhenzhou Fan +8
We propose PostCam, a streamlined framework for novel-view video generation that achieves superior detail preservation and precise camera trajectory editing in dynamic scenes. Curr…
StarGen: A Spatiotemporal Autoregression Framework with Video Diffusion Model for Scalable and Controllable Scene Generation
Shangjin Zhai, Zhichao Ye, Jialin Liu +10
Recent advances in large reconstruction and generative models have significantly improved scene reconstruction and novel view generation. However, due to compute limitations, each…
PGSR: Planar-based Gaussian Splatting for Efficient and High-Fidelity Surface Reconstruction
Danpeng Chen, Hai Li, Weicai Ye +7
Recently, 3D Gaussian Splatting (3DGS) has attracted widespread attention due to its high-quality rendering, and ultra-fast training and rendering speed. However, due to the unstru…
Long-term Visual Localization with Mobile Sensors
Shen Yan, Yu Liu, Long Wang +6
Despite the remarkable advances in image matching and pose estimation, image-based localization of a camera in a temporally-varying outdoor environment is still a challenging probl…
EC-SfM: Efficient Covisibility-based Structure-from-Motion for Both Sequential and Unordered Images
Zhichao Ye, Chong Bao, Xin Zhou +3
Structure-from-Motion is a technology used to obtain scene structure through image collection, which is a fundamental problem in computer vision. For unordered Internet images, SfM…
Robust Keyframe-based Dense SLAM with an RGB-D Camera
Haomin Liu, Chen Li, Guojun Chen +3
In this paper, we present RKD-SLAM, a robust keyframe-based dense SLAM approach for an RGB-D camera that can robustly handle fast motion and dense loop closure, and run without tim…
ENFT: Efficient Non-Consecutive Feature Tracking for Robust Structure-from-Motion
Guofeng Zhang, Haomin Liu, Zilong Dong +3
Structure-from-motion (SfM) largely relies on feature tracking. In image sequences, if disjointed tracks caused by objects moving in and out of the field of view, occasional occlus…
