UG^2+ Track 2: A Collective Benchmark Effort for Evaluating and Advancing Image Understanding in Poor Visibility Environments [article]

Ye Yuan, Wenhan Yang, Wenqi Ren, Jiaying Liu, Walter J. Scheirer, Zhangyang Wang
2020 arXiv   pre-print
In its second track, we focus on object or face detection in poor visibility enhancements caused by bad weathers (haze, rain) and low light conditions.  ...  To provide a more thorough examination and fair comparison, we introduce three benchmark sets collected in real-world hazy, rainy, and low-light conditions, respectively, with annotate objects/faces annotated  ...  For each sub- challenge, we collect a new benchmark dataset captured in realistic poor-visibility environments with real image artifacts caused by rain, haze, insufficiency of light.  ...

Maintaining Common Ground in Dynamic Environments

Takuma Udagawa, Akiko Aizawa
2021 Transactions of the Association for Computational Linguistics  
In this work, we propose a novel task setting to study the ability of both creating and maintaining common ground in dynamic environments.  ...  Common grounding is the process of creating and maintaining mutual understandings, which is a critical aspect of sophisticated human communication.  ...  Secondly, we focus on synthesizing the entity movements, as popularized in the recent video understanding benchmarks (Girdhar and Ramanan, 2020; Yi et al., 2020; Bakhtin et al., 2019) .  ...
