Function Documentation

convert()

std::unique_ptr< MemImage > convert	(	cv::Mat &	matIn,
		std::optional< PixelType >	targetType,
		bool	convertBGR2RGB = true )

Converts an OpenCV image to a MemImage.

Parameters

matIn	The input image
targetType	The PixelType the returned image should have, if not given a target format is chosen that matches the pixel format of matIn. (default is std::nullopt)
convertBGR2RGB	Only for three-channel color images: whether to convert the OpenCV-default BGR format to the RGB format used in MemImage (default is true)

Returns

a new MemImage

convertOpenCVDistortionToDeformation()

std::shared_ptr< GlDenseDeformation > convertOpenCVDistortionToDeformation	(	const Image &	imgDesc,
		const std::array< double, 5 > &	distCoeffs,
		const mat3 &	Kin,
		const mat3 &	Kout,
		bool	rescaleByExtent = true,
		bool	flipY = false )

Converts OpenCV undistort map to GlDenseDeformation.

cv::initUndistortRectifyMap If

Parameters

rescaleByExtent	is false, output deformation is in pixel coordinates. Otherwise output deformation is in pixel coordinates component wise divided by extent of
imgDesc.
flipY	determins whether to flip the Y coordinate from OpenCV representation

convertOpenCVDistortionToInverseDeformation()

std::shared_ptr< GlDenseDeformation > convertOpenCVDistortionToInverseDeformation	(	int	width,
		int	height,
		const std::array< double, 5 > &	distCoeffs,
		const mat3 &	Kin,
		bool	flipY = false )

Obtains a deformation field to model camera distortion using OpenCV.

Parameters

distCoeffs	are OpenCV-style distortion coefficients
Kin	is the camera matrix (onto pixel coordinates).
flipY	determins whether to flip the Y coordinate from OpenCV representation
