Now-a-days, much of the video surveillance systems require to manually setting a motion detection sensitivity level to generate motion alarms. The performance of motion detection algorithms, embedded in CCTV camera and digital video recorder usually depends upon the preselected motion sensitivity level, which works in all environmental conditions. Due to the preselected sensitivity level, false alarms and detection failures usually exist in video surveillance systems. The proposed motion detection model based upon variational energy provides a robust detection method at various illumination changes and noise levels of image sequences without tuning any parameter manually. The authors analyze the structure mathematically and demonstrate the effectiveness of the proposed model with numerous experiments in various environmental conditions.
