Dim Small Target Detection and Tracking: A Novel Method Based on Temporal Energy Selective Scaling and Trajectory Association

no code implementations15 May 2024 Weihua Gao, Wenlong Niu, Wenlong Lu, Pengcheng Wang, Zhaoyuan Qi, Xiaodong Peng, Zhen Yang

We use a well-designed function to amplify the transient disturbance, suppress the background and noise components, and output the trajectory of the target on the multi-frame detection unit.

Active Prompting with Chain-of-Thought for Large Language Models

2 code implementations23 Feb 2023 Shizhe Diao, Pengcheng Wang, Yong Lin, Rui Pan, Xiang Liu, Tong Zhang

For this purpose, we propose a solution to the key problem of determining which questions are the most important and helpful ones to annotate from a pool of task-specific queries.
