Syntax

public BackgroundSubtractorKNN(
	int history,
	double dist2Threshold,
	bool detectShadows
)

Public Sub New ( 
	history As Integer,
	dist2Threshold As Double,
	detectShadows As Boolean
)

public:
BackgroundSubtractorKNN(
	int history, 
	double dist2Threshold, 
	bool detectShadows
)

new : 
        history : int * 
        dist2Threshold : float * 
        detectShadows : bool -> BackgroundSubtractorKNN

history: Type: SystemInt32
Length of the history.
dist2Threshold: Type: SystemDouble
Threshold on the squared distance between the pixel and the sample to decide whether a pixel is close to that sample. This parameter does not affect the background update.
detectShadows: Type: SystemBoolean
If true, the algorithm will detect shadows and mark them. It decreases the speed a bit, so if you do not need this feature, set the parameter to false.
