ColorThresholdParams

Description

This structure contains parameters for color-based thresholding of an image.

Structure fields and default values (if defined) are described below:

• Pixel RgbColor - Color to compare the image to
• float ChromaAmount = 0.7f - Proportion of chromatic information in distance computation
• float MaxDifference = 5 - Maximum difference between image pixel and model color
• float Hysteresis - Defines how much the threshold criterion is lowered for pixels neighboring with other foreground pixels

struct ColorThresholdParams
{
	Pixel	RgbColor;
	float	ChromaAmount;
	float	MaxDifference;
	float	Hysteresis;

	explicit ColorThresholdParams
	(
		 float ChromaAmount_ = 0.7f,
		 float MaxDifference_ = 5 
	) :
		 ChromaAmount(ChromaAmount_),
		 MaxDifference(MaxDifference_) 
	{}

	float ChromaAmount( void ) const	{ return ChromaAmount;	};
	float MaxDifference( void ) const	{ return MaxDifference;	};
	float Hysteresis( void ) const		{ return Hysteresis;	};
