A target-aware enhancer (TAE) framework addresses severe image degradation in nighttime UAV tracking by integrating explicit target-location guidance and an adaptive multi-curve illumination fusion mechanism. TAE consistently improved the performance of state-of-the-art trackers on a newly introduced DarkSOT benchmark, which offers a large-scale, diverse resource for low-light UAV tracking research.

Key insights

  • Explicit target-location guidance is critical for low-light image enhancement in tracking, as it effectively focuses enhancement on foreground objects, preserving features and suppressing background noise.
  • An adaptive multi-curve fusion mechanism, integrating multiple complementary transformations, offers a more robust and refined approach to illumination adjustment than single-curve models for diverse low-light degradations.
  • The construction of a large-scale, diverse, and well-annotated benchmark dataset is essential for driving systematic development and standardized evaluation of algorithms in challenging domains like nighttime UAV tracking.
