Robust Visual Tracking Based on Adaptive Extraction and Enhancement of Correlation Filter

IEEE Access, 2019
In recent years, correlation filter (CF)-based tracking methods have demonstrated competitive performance. However, conventional CF-based methods suffer from unwanted boundary effects because of the periodic assumption of the training and detection ...

Trends and Interannual Variability of the Hydroxyl Radical in the Remote Tropics During Boreal Autumn Inferred From Satellite Proxy Data

Geophysical Research Letters
Despite its importance for the global oxidative capacity, spatially resolved trends and variability of the hydroxyl radical (OH) are poorly constrained. We demonstrate the utility of a tropospheric column OH (TCOH) product, created from machine learning ...

A Funnel-Based Framework for Quantitative Safety Metric Construction and Safety-Metric-Driven Control Synthesis of Automatic Carrier Landing Systems

Aerospace
Current research on Automatic Carrier Landing Systems (ACLSs) primarily focuses on guidance and control performance metrics. However, safety metrics that quantitatively characterize the safe region of ACLSs are equally crucial for guaranteeing safe ...
