SCULPT: Subtractive Composition for 3D Part Generation
Sikuang Li, Chen Yang, Jiemin Fang +5
Part-aware 3D generation aims to create digital assets that are coherent as complete objects while exposing structural parts for editing, material assignment, animation, and reuse.…
Hit-and-Run Mixes as Fast as the Ball Walk
Ruizhe Zhang
Let be an isotropic convex body. We prove that the hit-and-run walk, started from any -warm distribution, reaches total-variation distance f…
Toward Robust and 3D-Aware RGB-NIR Imaging in the Dark
Muyao Niu, Mingze Ma, Yifan Zhan +5
Robust low-light imaging remains challenging for the community. Recent studies have explored fusing Near-Infrared (NIR) with noisy RGB to achieve improved enhancement, yet most met…
AlayaWorld: Interactive Long-Horizon World Modeling -- Full Technical Report
AlayaWorld Team, Kaipeng Zhang, Chuanhao Li +15
Unlike conventional video game development, which relies on labor-intensive pipelines for asset production, animation, physics, and programming, video world models generate interac…
AlayaWorld: Long-Horizon and Playable Video World Generation
AlayaWorld Team, Kaipeng Zhang, Chuanhao Li +14
Game worlds have traditionally been built through labor-intensive production pipelines, making them costly to develop, difficult to customization, and expensive to modify after dep…
MoECodec: Image Compression for joint human and machine perception via Mixture-of-Experts
Jiancheng Zhao, Xiang Ji, Yifan Zhan +2
Image compression for machines calls for a unified codec that serves multiple downstream vision tasks. Existing approaches either adopt task-specific end-to-end designs, raising pa…
