Detailed Description

template<class TImageType, class THistogramFrequencyContainer = DenseFrequencyContainer2>
class itk::Statistics::ScalarImageToRunLengthFeaturesFilter< TImageType, THistogramFrequencyContainer >

This class computes run length descriptions from an image.

By default, run length features are computed for each spatial direction and then averaged afterward, so it is possible to access the standard deviations of the texture features. These values give a clue as to texture anisotropy. However, doing this is much more work, because it involved computing one for each offset given. To compute a single matrix using the first offset, call FastCalculationsOn(). If this is called, then the texture standard deviations will not be computed (and will be set to zero), but texture computation will be much faster.

This class is templated over the input image type.

Template Parameters: The image type, and the type of histogram frequency container. If you are using a large number of bins per axis, a sparse frequency container may be advisable. The default is to use a dense frequency container.

Inputs and parameters:

An image
A mask defining the region over which texture features will be calculated. (Optional)
The pixel value that defines the "inside" of the mask. (Optional, defaults to 1 if a mask is set.)
The set of features to be calculated. These features are defined in the HistogramToRunLengthFeaturesFilter class.
The number of intensity bins. (Optional, defaults to 256.)
The set of directions (offsets) to average across. (Optional, defaults to {(-1, 0), (-1, -1), (0, -1), (1, -1)} for 2D images and scales analogously for ND images.)
The pixel intensity range over which the features will be calculated. (Optional, defaults to the full dynamic range of the pixel type.)
The distance range over which the features will be calculated. (Optional, defaults to the full dynamic range of double type.)

In general, the default parameter values should be sufficient.

Outputs: (1) The average value of each feature. (2) The standard deviation in the values of each feature.
