Detailed Description

template<typename TInputImage, typename TOutputImage>
class itk::MultiResolutionPyramidImageFilter< TInputImage, TOutputImage >

Framework for creating images in a multi-resolution pyramid.

MultiResolutionPyramidImageFilter provides a generic framework to to create a image pryamid according to a user defined multi-resolution schedule.

The multi-resolution schedule is specified in terms for shrink factors at each multi-resolution level for each dimension.

A user can either use the default schedules or specify each factor in the schedules directly.

The schedule is stored as an unsigned int matrix. An element of the table can be access via the double bracket notation: table[resLevel][dimension]

For example: 8 4 4 4 4 2

is a schedule for two computation level. In the first (coarest) level the image is reduce by a factor of 8 in the column dimension, factor of 4 in the row dimension and factor of 4 in the slice dimension. In the second level, the image is reduce by a factor of 4 in the column dimension, 4 is the row dimension and 2 in the slice dimension.

The method SetNumberOfLevels() set the number of computation levels in the pyramid. This method will allocate memory for the multi-resolution schedule table. This method generates defaults tables with the starting shrink factor for all dimension set to 2^(NumberOfLevel - 1). All factors are halved for all subsequent levels. For example if the number of levels was set to 4, the default table is:

8 8 8 4 4 4 2 2 2 1 1 1

The user can get a copy of the schedule via GetSchedule() They may make alteration and reset it using SetSchedule().

A user can create a default table by specifying the starting shrink factors via methods SetStartingShrinkFactors() The factors for subsequent level is generated by halving the factor or setting to one, depending on which is larger.

For example, for 4 levels and starting factors of 8,8,4 the default table would be:

8 8 4 4 4 2 2 2 1 1 1 1

When this filter is updated, NumberOfLevels outputs are produced. The N'th output correspond to the N'th level of the pyramid.

To generate each output image, Gaussian smoothing is first performed using a DiscreteGaussianImageFilter with variance (shrink factor / 2)^2. The smoothed image is then downsampled using a ResampleImageFilter.

Note that even if the shrink factors are all equal to one, a smoothing will still be applied. The output at the finest level of the pyramid will thus typically be a smoothed version of the input.

This class is templated over the input image type and the output image type.

This filter uses multithreaded filters to perform the smoothing and downsampling.

This filter supports streaming.

MultiResolutionPyramidImageFilter requires a larger input requested region than the output requested regions to accommodate the shrinkage and smoothing operations. As such, MultiResolutionPyramidImageFilter needs to provide an implementation for GenerateInputRequestedRegion(). The original documentation of this method is below.

MultiResolutionPyramidImageFilter produces images which are of different resolution and different pixel spacing than its input image.

virtual

Set the number of multi-resolution levels. The matrix containing the schedule will be resized accordingly. The schedule is populated with default values. At the coarset (0) level, the shrink factors are set 2^(nlevel - 1) for all dimension. These shrink factors are halved for subsequent levels. The number of levels is clamped to a minimum value of 1.

Set a multi-resolution schedule. The input schedule must have only ImageDimension number of columns and NumberOfLevels number of rows. For each dimension, the shrink factor must be non-increasing with respect to subsequent levels. This function will clamp shrink factors to satisify this condition. All shrink factors less than one will also be clamped to the value of 1.
