Detailed Description

template<int SPLINEORDER = 2>
class vigra::AffineMotionEstimationOptions< SPLINEORDER >

Option object for affine registration functions.

The template parameter SPLINEORDER (default: 2) specifies the order of interpolation for the intensities at non-integer image coordinates.

Member Function Documentation

splineOrder()

template<int SPLINEORDER = 2>

template<int NEWORDER>

AffineMotionEstimationOptions< NEWORDER > splineOrder

(

)

const

Change the spline order for intensity interpolation.

Usage:

// use linear interpolation
AffineMotionEstimationOptions<>().splineOrder<1>();

Default: order = 2 (quadratic interpolation)

burtFilterCenterStrength()

template<int SPLINEORDER = 2>

AffineMotionEstimationOptions & burtFilterCenterStrength

(

double

center

)

Define amount of smoothing before subsampling to the next pyramid level.

Pyramids are created with the Burt filter:

[0.25 - center / 2.0, 0.25, center, 0.25, 0.25 - center / 2.0]

center must thus be between 0.25 and 0.5, and the smaller it is, the more smoothing is applied.

Default: 0.4 (moderate smoothing)

highestPyramidLevel()

template<int SPLINEORDER = 2>

AffineMotionEstimationOptions & highestPyramidLevel

(

unsigned int

level

)

Define the highest level of the image pyramid.

The original image is at level 0, and each level downsamples the image by 1/2.

Default: 4 (16-fold downsampling)

iterationsPerLevel()

template<int SPLINEORDER = 2>

AffineMotionEstimationOptions & iterationsPerLevel

(

unsigned int

iter

)

Number of Gauss-Newton iterations per level.

Default: 4

useGaussianPyramid()

template<int SPLINEORDER = 2>

AffineMotionEstimationOptions & useGaussianPyramid

(

bool

f = true

)

Base registration on a Gaussian pyramid.

Images are registered such that the similarity in intensity is maximized.

Default: true

useLaplacianPyramid()

template<int SPLINEORDER = 2>

AffineMotionEstimationOptions & useLaplacianPyramid

(

bool

f = true

)

Base registration on a Laplacian pyramid.

Images are registered such that the similarity in second derivatives (=Laplacian operator results) is maximized.

Default: false
