Adaptive BP-RRC mixture model for background subtraction

In the real-time segmentation of the moving objects in a image sequence, methods based on background subtraction are used widely. Bi-polar Radial Reach Correlation (BP-RRC) has realized robust background subtraction by evaluating a local texture per pixel, suppressing the influence of brightness change. However, this method has a fault that is affected by the local illumination change of a background. This paper proposes a robust and stabilized background subtraction algorithm which can cope with texture change of various illumination changes by improving this texture background model. We verified the proposed method using the image sequence including a loose lighting change and a rapid lighting change, and adaptability higher than the conventional method on the sudden illumination changes was attained as a result of verification.
