Constructor & Destructor Documentation

BayerConverter() [1/2]

icl::core::BayerConverter::BayerConverter	(	const std::string &	pattern = "RGGB",
		const std::string &	method = "bilinear"
	)

creates a bayer converter with given string-based parameters

BayerConverter() [2/2]

icl::core::BayerConverter::BayerConverter	(	bayerPattern	eBayerPattern,
		bayerConverterMethod	eConvMethod = bilinear,
		const utils::Size &	sizeHint = utils::Size::null
	)

creates a new BayerConverter instances

The given size hint can be used to accellerate the first apply call, where the internal working buffer's size is adapted on demand

Member Function Documentation

apply()

void icl::core::BayerConverter::apply	(	const Img8u *	src,
		ImgBase **	dst
	)

converts the source image with bayer pattern into the

given destination image. Dst will become an Img8u

bilinearInterpolation()

void icl::core::BayerConverter::bilinearInterpolation ( const Img8u *  poBayerImg )

private

clearBorders()

void icl::core::BayerConverter::clearBorders ( icl8u *  rgb, int  sx, int  sy, int  w  )

private

clip()

void icl::core::BayerConverter::clip ( int *  iIn, icl8u *  iOut  )

inlineprivate

convert_bayer_to_gray()

static void icl::core::BayerConverter::convert_bayer_to_gray ( const Img8u &  src, Img8u &  dst, const std::string &  pattern  )

static

static utility method to convert a given bayer image to grayscale

This is much faster than applying the standard bayer method, which will run though the image several times:

• creating the interlearved rgb-image
• converting the interleaved rgb-image to a planar rgb image
• converting the planar rgb image to a one channel gray scale image

The destination image is adapted in size and format
