IDEAL-Bench: Indoor Dataset and Evaluation suite for Analyzing 3D Layout reasoning
Yuening Cai, Junwei Zhou, Youran Qu +1
Spatial question answering is the dominant paradigm for evaluating spatial intelligence in Vision-Language Models (VLMs), but it leaves a complementary axis of spatial competence u…
GENA3D: Generative Amodal 3D Modeling by Bridging 2D Priors and 3D Coherence
Junwei Zhou, Yu-Wing Tai
Generating complete 3D objects under partial occlusions (i.e., amodal scenarios) is a practically important yet challenging problem, as large portions of object geometry are unobse…
Perceive-then-Plan: Layout-as-Policy for Monocular 3D Scene Layout Estimation
Junwei Zhou, Yu-Wing Tai
Building structured 3D scene layouts from a single image requires reconciling visual observations with physical and spatial constraints, a challenge that is difficult to address wi…
Distributed Image Compression with Multimodal Side Information at Extremely Low Bitrates
Guojun Xu, Mingyang Zhang, Jianwen Xiang +3
Distributed Image Compression (DIC) is crucial for multi-view transmission, especially when operating at extremely low bitrates (< 0.1 bpp). Its core challenge is effectively utili…
CoCo4D: Comprehensive and Complex 4D Scene Generation
Junwei Zhou, Xueting Li, Lu Qi +1
Existing 4D synthesis methods primarily focus on object-level generation or dynamic scene synthesis with limited novel views, restricting their ability to generate multi-view consi…
Layout-your-3D: Controllable and Precise 3D Generation with 2D Blueprint
Junwei Zhou, Xueting Li, Lu Qi +1
We present Layout-Your-3D, a framework that allows controllable and compositional 3D generation from text prompts. Existing text-to-3D methods often struggle to generate assets wit…
