It Abstract. This paper is aimed at investigating background subtraction based on second-order polynomial models. Recently, preliminary results suggested that quadratic models hold the potential to yield superior performance in handling common disturbance factors, such as noise, sudden illumination changes and variations of camera parameters, with respect to state-of-the-art background subtraction methods. Therefore, based on the formalization of background subtraction as Bayesian regression of a second-order polynomial model, we propose here a thorough theoretical analysis aimed at identifying a family of suitable models and deriving the closed-form solutions of the associated regression problems.

Di Stefano Thanks to this approach, gradual as well as sudden photometric distortions do not yield false positives provided that they are explained by the model. Thus, the main issue concerns the choice of the a priori model: in principle, the more restrictive such a model, the higher is the ability to detect changes (sensitivity) but the lower is robustness to sources of disturbance (specificity). Some proposals assume disturbance factors to yield linear intensity transformations [4, 5]. Nevertheless, as discussed in [6], many non-linearities may arise in the image formation process, so that a more liberal model than linear is often required to achieve adequate robustness in practical applications.
