void opentl::cvprocess::SurfFeatures::copyAllMatches

(

opentl::core::cvdata::SurfFeatures &

surfFeatures

)

Just copy all matches as inliers (no outlier removal).

Parameters:

surfFeatures

Input and output matched keypoints

void opentl::cvprocess::SurfFeatures::detectKeypoints	(	const opentl::core::cvdata::Image &	img,
		opentl::core::cvdata::SurfFeatures &	surfFeatures,
		opentl::core::cvdata::Image *	mask = NULL
	)

SURF keypoints detection from a given image.

Parameters:

	img	Input image
	surfFeatures	Output detected keypoints
	mask	Binary mask image (for detection only in a ROI)

void opentl::cvprocess::SurfFeatures::drawCorrespondences	(	const opentl::core::cvdata::SurfFeatures &	surfFeatures,
		const opentl::core::cvdata::Image &	refImg,
		const opentl::core::cvdata::Image &	currImg,
		opentl::core::cvdata::Image &	outImg,
		CvScalar	lineColor
	)

Draw inlier object-image matchings (after RANSAC) - optionally, draw also the estimated homography transform.

Parameters:

	surfFeatures	Input matched keypoints
	refImg	Model image
	currImg	Current image
	outImg	Output image (with both images)
	lineColor	Color of matching lines

void opentl::cvprocess::SurfFeatures::drawFeatures	(	const opentl::core::cvdata::SurfFeatures &	surfFeatures,
		opentl::core::cvdata::Image &	img,
		CvScalar	color
	)

Draw model or image features onto an image.

Parameters:

	surfFeatures	Detected keypoints
	img	Image for drawing
	color	Color of keypoints (small circles)

void opentl::cvprocess::SurfFeatures::drawInlierCorrespondences	(	const opentl::core::cvdata::SurfFeatures &	surfFeatures,
		const opentl::core::cvdata::Image &	refImg,
		const opentl::core::cvdata::Image &	currImg,
		opentl::core::cvdata::Image &	outImg,
		CvScalar	lineColor,
		CvRect *	rectangleHomography = NULL
	)

Draw inlier object-image matchings (after RANSAC) - optionally, draw also the estimated homography transform.

Parameters:

	surfFeatures	Input matched keypoints
	refImg	Model image
	currImg	Current image
	outImg	Output image (with both images)
	lineColor	Color of matching lines
	rectangleHomography	(optional) pointer to a rectangle in object image, to be transformed with the estimated homography

int opentl::cvprocess::SurfFeatures::matchKeypoints	(	opentl::core::cvdata::SurfFeatures &	objectFeatures,

	)

Match object-image keypoints (without RANSAC).

Parameters:
