Description

Two additional background subtraction algorithms. These algorithms do not support getBackgroundImage (and probably never will).

Arguments

:: PrimMonad m
=> Maybe Int32	Number of frames used to initialize the background models.
-> Maybe Double	Threshold value, above which it is marked foreground, else background.
-> m (BackgroundSubtractorGMG (PrimState m))

Arguments

:: PrimMonad m
=> Maybe Int32	Length of the history.
-> Maybe Int32	Number of Gaussian mixtures.
-> Maybe Double	Background ratio.
-> Maybe Double	Noise strength (standard deviation of the brightness or each color channel). 0 means some automatic value.
-> m (BackgroundSubtractorMOG (PrimState m))
