From: Background Subtraction for Automated Multisensor Surveillance: A Comprehensive Review
A typical example of ill-posed BG subtraction issue: the oscillating background. (a) A frame representing the background scene, where a tree is oscillating, as highlighted by the arrows. (b) A moving object passes in front of the scene. (c) The ground truth, highlighting only the real foreground object. (d) The result of the background subtraction employing a standard method: the moving branches are detected as foreground.
