Detailed Description

AKAZE Class Declaration.

Constructor & Destructor Documentation

AKAZE()

aliceVision::feature::AKAZE::AKAZE	(	const image::Image< float > &	image,
		const AKAZEOptions &	options
	)

Constructor.

Parameters

[in]	image	Input image
[in]	options	AKAZE configuration options

Member Function Documentation

computeMainOrientation()

void aliceVision::feature::AKAZE::computeMainOrientation	(	AKAZEKeypoint &	keypoint,
		const image::Image< float > &	Lx,
		const image::Image< float > &	Ly
	)		const

This method computes the main orientation for a given keypoint.

Parameters

[in,out]	keypoint	Input keypoint
[in]	Lx	X derivatives
[in]	Ly	Y derivatives

Note

The orientation is computed using a similar approach as described in the original SURF method. See Bay et al., Speeded Up Robust Features, ECCV 2006

featureDetection()

void aliceVision::feature::AKAZE::featureDetection

(

std::vector< AKAZEKeypoint > &

keypoints

)

const

Parameters

[in,out]

keypoints

AKAZE keypoints

getSlices()

const std::vector<TEvolution>& aliceVision::feature::AKAZE::getSlices ( ) const

inline

Get scale space slices.

Returns

slices

gridFiltering()

void aliceVision::feature::AKAZE::gridFiltering

(

std::vector< AKAZEKeypoint > &

keypoints

)

const

Grid filtering of the detected keypoints.

Parameters

[in,out]

keypoints

AKAZE keypoints

subpixelRefinement() [1/2]

bool aliceVision::feature::AKAZE::subpixelRefinement	(	AKAZEKeypoint &	keypoint,
		const image::Image< float > &	Ldet
	)		const

Sub-pixel refinement of the detected keypoint.

Parameters

[in,out]

keypoint

AKAZE keypoint

subpixelRefinement() [2/2]

void aliceVision::feature::AKAZE::subpixelRefinement

(

std::vector< AKAZEKeypoint > &

keypoints

)

const

Parameters

[in,out]

keypoints

AKAZE keypoints
