Detailed Description

template<class VoxelType>
class ImagePyramid< VoxelType >

Class that implements a mulit-resolution image pyramid. This class implements a decimating multi-resolution image pyramid. From one level to the next the image resolution is halved.

GenerateLevels()

template<class VoxelType >

void ImagePyramid< VoxelType >::GenerateLevels	(	const nifti_image *const	imageIn,
		unsigned int	numberOfLevels,
		unsigned int	numberOfLevelsToPerform,
		unsigned int	minNumberOfVoxelsPerDim = 1,
		float(*)	minVoxDim[3] = nullptr
	)

Generate the pyramid levels

Parameters

imageIn	Pointer to the nifti input image
numberOfLevels	Total number of pyramid levels. Will be increased, if numberOfLevelsToPerform is larger than this.
numberOfLevelsToPerform	Total number of levels to perform. If it is larger than numberOfLevels, it will be updated.
minNumberOfVoxelsPerDim	The minimum number of voxels per level below which a dimension will not be subsampled.
minVoxDim	The minimal voxel dimension. If minVoxDim is provided, then the image is only downsampled if voxel size in the resampled image <= minVoxDim.

Todo:

Need to find a solution if slope is zero. If this is the case, the input data will be blacked out.

GetLevel()

template<class VoxelType >

nifti_image * ImagePyramid< VoxelType >::GetLevel ( unsigned int  level )

inline

Get the pointer to a nifti image that represents a level of the decimating Gaussian image pyramid.

Parameters

level

The requested level.

Returns

A pointer to the requested pyramid level. Will return NULL if the requested level does not exist.

operator=()

template<class VoxelType >

ImagePyramid< VoxelType > & ImagePyramid< VoxelType >::operator=

const ImagePyramid< VoxelType > &
