Abstract

This work demonstrates the effectiveness of the median filter combined with morphological operators in the detection of anomalies in video surveillance of scenes of natural environment. Natural environment is characterized by backgrounds that are not static but whose dynamics are limited and do not include the appearance or disappearance of background objects in the scene. Examples include background images with seawater or river surfaces, or landscapes with trees, in which the wind produces waves and other movements of limited amplitude. The performance on four publicly available benchmark videos is compared to that of other published state-of-the-art works. The results obtained are promising.
