Constructor & Destructor Documentation

virtual SiftGPUWrapper::~SiftGPUWrapper ( ) [virtual]

Destructor

SiftGPUWrapper::SiftGPUWrapper ( ) [private]

private constructor, because of singleton

Member Function Documentation

void SiftGPUWrapper::cvMatToSiftGPU	(	const cv::Mat &	image,
		unsigned char *	siftImage
	)		const `[private]`

Building a siftgpu compatible unsigned char pointer out of the image cv::Mat (converts a cv matrix into an OpenGL texture array)

Parameters:

image	the image
siftImage	the transformed image (output)

static void SiftGPUWrapper::destroyInstance ( ) [static]

void SiftGPUWrapper::detect	(	const cv::Mat &	image,
		cv::vector< cv::KeyPoint > &	keypoints,
		std::vector< float > &	descriptors,
		const cv::Mat &	mask = `cv::Mat()`
	)		const

Method, which is used for calculating the features and descriptors. The first parameter is the image, the second one a reference to a keypoint vector and the third parameter can be used for defining a mask

Parameters:

image	the image
keypoints	a cv::vector of cv::Keypoints, which is used for storing the keypoints
mask	a mask (see OpenCV)

Returns:: a pointer to the descriptor values

static SiftGPUWrapper* SiftGPUWrapper::getInstance ( ) [static]

Return instance of the singleton class

void SiftGPUWrapper::initializeMatcher ( ) [private]

int SiftGPUWrapper::match	(	const std::vector< float > &	descriptors1,
		int	num1,
		const std::vector< float > &	descriptors2,
		int	num2,
		std::vector< cv::DMatch > *	matches
	)

Is used for matching two descriptors

Parameters:

descriptors1	the first descriptor
num1	size of the first descriptor
descriptors2	the second descriptor
num2	size of the second descriptor
matches	is used to store the matches
