4D-Bench: Benchmarking Multi-modal Large Language Models for 4D Object Understanding

Wenxuan Zhu, Bing Li, Cheng Zheng, Jinjie Mai, Jun Chen, Letian Jiang +5

ICCV 2025poster

Multimodal Large Language Models (MLLMs) have demonstrated impressive 2D image/video understanding capabilities.However, there are no publicly standardized benchmarks to assess the abilities of MLLMs in understanding the 4D objects.In this paper, we introduce 4D-Bench, the first benchmark to evaluat…

SMILE: Infusing Spatial and Motion Semantics in Masked Video Learning

Fida Mohammad Thoker, Letian Jiang, Chen Zhao, Bernard Ghanem

CVPR 2025poster

Masked video modeling, such as VideoMAE, is an effective paradigm for video self-supervised learning (SSL). However, they are primarily based on reconstructing pixel level details on natural videos which have substantial temporal redundancy, limiting their capability for semantic representation and…
