DarkLighter: Light up the Darkness for UAV Tracking
Code and demo videos of DarkLighter---a low-light enhancer towards facilitating UAV tracking in the dark.
Abstract
Recent years have witnessed the fast evolution and promising performance of the convolutional neural network (CNN)-based trackers, which aims at imitating biological visual systems. However, current CNN-based trackers can hardly generalize well to low-light scenes that are commonly lacked in the existing training set. In indistinguishable night scenarios frequently encountered in tracking-based applications on unmanned aerial vehicle (UAV), the robustness of the state-of-the-art trackers drops significantly. To facilitate aerial tracking in the dark through a general fashion, this work proposes an image enhancer namely DarkLighter, which dedicates to alleviate the impact of poor illumination conditions and noises iteratively. A lightweight network, i.e., LE-Net, is trained to efficiently estimate illumination layers and noise layers jointly. Experiments are conducted with several SOTA trackers on numerous UAV dark tracking scenarios. Exhaustive evaluations demonstrate the reliability and universality of DarkLighter, with high efficiency. Moreover, DarkLighter has further been implemented onboard a typical UAV system, real-world UAV tracking tests at night verify its practicability and dependability.
