DM-KG: A Novel Method for Boosting Spatial Cognition of Vision-Language Models in Street View Imagery

Xinyue Xu, Zheng Zhang, Kunyang Ma, Ge Zhu, Lianshuai Cao, Lei Wang, et al.

As vision-language models (VLMs) are increasingly deployed in geospatial question answering and visual scene understanding, improving their spatial cognition capability on street view imagery for complex logical reasoning has emerged as a key research priority. However, existing…

Stage-Transition Dense Reward Modeling for Reinforcement Learning

Yang Yang, Bingjie Chen, Zihan Wang, Yizhe Li, Guoping Pan, Yi Cheng, et al.

Reinforcement learning for long-horizon robotic manipulation is often limited by sparse and delayed rewards, while manually designing dense shaping signals is costly and brittle to changes in environments and object configurations. This work proposes Stage-Transition Dense Reward…

Research on Mass Prediction of Maize Kernel Based on Machine Vision and Machine Learning Algorithm

Yang Yu, Chenlong Fan, Qibin Li, Qinhao Wu, Yi Cheng, Xin Zhou, et al.

The yield assessment process during maize harvesting is a necessary means to ensure farmers’ economic benefits and stable agricultural production. Predicting the mass of maize kernels is an important condition for yield detection. This study proposes a maize kernel mass predictio…
