Joint False Alarm Dataset (JFAD)

This repository presents the Joint False Alarm Dataset (JFAD). The dataset is designed to support the training, evaluation, and validation of deep learning models for thermal anomaly detection and false alarm reduction in terrestrial remote sensing scenarios. JFAD provides a comprehensive representation of thermal interference sources that commonly trigger false detections, making it a strong benchmark for developing robust cascade-based detection architectures. JFAD was constructed by consolidating two complementary repositories: the Addressing False Alarm Situations (AFAS) dataset and the Thermal Anomaly (TA) dataset. Together, these collections characterize a broad spectrum of challenging thermal conditions across both the near-infrared (NIR) and long-wave infrared (LWIR) domains. The dataset includes diverse environments such as urban infrastructure monitoring, rural surveillance, and wilderness fire-like anomaly scenarios. A key contribution of this dataset is the re-annotation of the TA subset, extending traditional bounding-box labels into pixel-level instance masks. This enables models to better distinguish filament-like structures such as powerlines from irregular thermal signatures caused by incipient fires, solar glint, or exhaust emissions, an essential requirement for minimizing false alarms in real-world deployments. Dataset Composition The JFAD dataset comprises a total of 6098 thermal images, aggregated from multiple measurement campaigns and established open benchmarks, including: 1) FLIR Advanced Driver Assistance Systems (ADAS) 2) TarDAL M3FD 3) Powerline Image Dataset (PID) 4) In-house thermal acquisitions across urban, rural, and wilderness settings The dataset reflects substantial cross-sensor variability, incorporating different platforms, resolutions, and monitoring conditions. For experimental evaluation, JFAD is divided into: 4308 training samples and 1790 validation samples Technical Specifications File Formats: JPEG, TXT, NPY Spectral Bands: NIR and LWIR Resolution Range: 160×120 up to 640×512 Cameras used: FLIR Tau 2, FLIR A615, FLIR A35, Seek Mosaic, and FLIR Lepton This repository contains the dataset used in our work.
