Segmentation of Moving Object Using Background Subtraction Method in Complex Environments
Santosh Kumar, Jigyendra Sen Yadav · Radioengineering · 2016
Background subtraction is an extensively used approach to localize the moving object in a video sequence.However, detecting an object under the spatiotemporal behavior of background such as rippling of water, moving curtain and illumination change or low resolution is not a straightforward task.To deal with the above-mentioned problem, we address a background maintenance scheme based on the updating of background pixels by estimating the current spatial variance along the temporal line.The work is focused to immune the variation of local motion in the background.Finally, the most suitable label assignment to the motion field is estimated and optimized by using iterated conditional mode (ICM) under a Markovian frame-work.Performance evaluation and comparisons with the other well-known background subtraction methods show that the proposed method is unaffected by the problem of aperture distortion, ghost image, and high frequency noise.
