static void opentl::cvprocess::CV::computeIntegralImage	(	opentl::core::cvdata::Image &	srcImage,
		unsigned int *	dstData
	)			[static]

Computes the integral image of an greyscale 1 channel input image in a recursive way.

Parameters:

	srcImage	Image to compute an integral image from
	dstData	destination data structure (MUST have the dimension of (width(srcImage)+1)*(height(srcImage)+1)). E.g. by doing a "new unsigned int[(w+1)*(h+1)];"

static void opentl::cvprocess::CV::convertHalcon2OpenCV	(	const unsigned char *	R,
		const unsigned char *	G,
		const unsigned char *	B,
		opentl::core::cvdata::Image &	outimg
	)			[static]

Copies a Halcon image to a OpenCV image (formats and sizes must match).

static std::size_t opentl::cvprocess::CV::countWhitePixels	(	const opentl::core::cvdata::Image &	inImage,
		unsigned int	xAct,
		unsigned int	yAct,
		unsigned int	width,
		unsigned int	height,
		unsigned int	whiteValue = 255
	)			[static]

Count the number of white pixels (= value of 255) of an 1 channel greyscale image).

Parameters:

	inImage	Image to count white pixels from
	xAct	Lower left x coordinate of the axis aligned bounding box to count from
	yAct	Lower left y coordinate of the axis aligned bounding box to count from
	width	Width of the axis aligned bounding box to count from
	height	Height of the axis aligned bounding box to count from
	whiteValue	value of a pixel to be considered white

Returns:

Returns the number of white pixels found inside the bounding box (region of interest)
