Background Subtractor module
Background Subtractor module based on the algorithm given in [Gold2012].
Takes a series of images and returns a sequence of mask uint8 images
of the same size, where 255 indicates Foreground and 0 represents
Background. This class implements an algorithm described in [Gold2012].
