Characterizing Anomalous Behavior of Moving Objects using Optical Flow Feature Extraction in Crowded Environment
Parul Saxena, Rakesh Singh Jadon · International Journal of Engineering and Technology · 2020
In this paper, a novel approach is proposed to detect an abnormal behaviour in a video.In order to provide security, it is necessary to analyze the behaviors of people and determine whether these behaviors are normal or abnormal.There are several keywords to refer to the abnormalities such as unusual, suspicious, anomalous and abnormal.In this paper, we refer opticalFlowFarneback method.After calculating optical flow and magnitudes using farneback method, we create an activity map using multiple frames to see the flow persistency over time.We have conducted experiments on various datasets and the results show that the proposed method provides 95% accuracy for UMN dataset.
