A new research paper explores the effectiveness of using frame-level labels for detecting small unmanned aerial vehicles (UAVs) in thermal video footage. The study analyzes an existing architecture that leverages presence/absence labels to train localization capabilities, even when spatial annotations are difficult to obtain. Results on two thermal infrared datasets, CST Anti-UAV and Anti-UAV410, indicate that classification training enhances target-related spatial responses, while readout training improves their consistent extraction. The research also found that distributing similar label counts across more videos improved localization hit rates, though detection under false-alarm constraints did not always improve and failures occurred with weak target signals or cross-dataset transfer.
