Public Attributes
float	alpha1
	How quickly we forget old background pixel values seen. Typically set to 0.1.

float	alpha2
	"Controls speed of feature learning". Depends on T. Typical value circa 0.005.

float	alpha3
	Alternate to alpha2, used (e.g.) for quicker initial convergence. Typical value 0.1.

float	delta
	Affects color and color co-occurrence quantization, typically set to 2.

bool	is_obj_without_holes
	If TRUE we ignore holes within foreground blobs. Defaults to TRUE.

int	Lc
	Quantized levels per 'color' component. Power of two, typically 32, 64 or 128.

int	Lcc
	Quantized levels per 'color co-occurrence' component. Power of two, typically 16, 32 or 64.

float	minArea
	Discard foreground blobs whose bounding box is smaller than this threshold.

int	N1c
	Number of color vectors used to model normal background color variation at a given pixel.

int	N1cc
	Number of color co-occurrence vectors used to model normal background color variation at a given pixel.

int	N2c
	Used to allow the first N1c vectors to adapt over time to changing background.

int	N2cc
	Used to allow the first N1cc vectors to adapt over time to changing background.

int	perform_morphing
	These erase one-pixel junk blobs and merge almost-touching blobs. Default value is 1.
