Implicit 4D Gaussian Splatting for Fast Motion with Large Inter-Frame Displacements
Seung-gyeom Kim, Areum Kim, Yongjae Yoo +1
Recent 4D Gaussian Splatting (4DGS) methods often fail under fast motion with large inter-frame displacements, where Gaussian attributes are poorly learned during training, and fas…
Reference-Free Assessment of Physical Consistency in World Model-based Video Generation
Yun Oh, Sukmin Yun
We introduce reference-free measures for evaluating the physical consistency of generated videos, combining relative and absolute approaches to assess fidelity. Although tools like…
Improving Visual Representation Alignment Generation with GRPO
Shentong Mo, Sukmin Yun
Recent diffusion transformers have demonstrated strong image synthesis capabilities but remain inefficient to train due to weak alignment between generative and discriminative repr…
LVRPO: Language-Visual Alignment with GRPO for Multimodal Understanding and Generation
Shentong Mo, Sukmin Yun
Unified multimodal pretraining has emerged as a promising paradigm for jointly modeling language and vision within a single foundation model. However, existing approaches largely r…
