Cross-Illumination Video Anomaly Detection Benchmark

Video anomaly detection is a critical problem with widespread applications in domains such as security surveillance. Most existing methods focus on video anomaly detection tasks under uniform illumination conditions. However, in the real world, the situation is much more complicated. Video anomalies are widespread across periods and under different illumination conditions, which can lead to the detector model incorrectly reporting high anomaly scores. To address this challenge, we design a benchmark framework for the cross-illumination video anomaly detection task. The framework restores videos under different illumination scales to the same illumination scale. This reduces domain differences between uniformly illuminated training videos and differently illuminated test videos. Additionally, to demonstrate the illumination change problem and evaluate our model, we construct three large-scale datasets with a wide range of illumination variations. We experimentally validate our approach on three cross-illuminance video anomaly detection datasets. Experimental results show that our method outperforms existing methods regarding detection accuracy and is more robust.
