Background Modeling with Extracted Dynamic Pixels for Pumping Unit Surveillance

Abstract EN

Background modeling plays an important role in the application of intelligent video surveillance.

Researchers have presented diverse approaches to support the development of dynamic background modeling.

However, in the case of pumping unit surveillance, traditional background modeling methods often mistakenly detect the periodic rotational pumping unit as the foreground object.

To address this problem here, we propose a novel background modeling method for foreground segmentation, particularly in dynamic scenes that include a rotational pumping unit.

In the proposed method, the ViBe method is employed to extract possible foreground pixels from the sequence frames and then segment the video image into dynamic and static regions.

Subsequently, the kernel density estimation (KDE) method is used to build a background model with dynamic samples of each pixel.

The bandwidth and threshold of the KDE model are calculated according to the sample distribution and extremum of each dynamic pixel.

In addition, the strategy of sample adjustment combines regular and real-time updates.

The performance of the proposed method is evaluated against several state-of-the-art methods applied to complex dynamic scenes consisting of a rotational pumping unit.

Experimental results show that the proposed method is available for periodic object motion scenario monitoring applications.
