Detailed Description

template<class TInputImage1, class TInputImage2>
class itk::DirectedHausdorffDistanceImageFilter< TInputImage1, TInputImage2 >

Computes the directed Hausdorff distance between the set of non-zero pixels of two images.

DirectedHausdorffDistanceImageFilter computes the distance between the set non-zero pixels of two images using the following formula:

where and are respectively the set of non-zero pixels in the first and second input images. It identifies the point that is farthest from any point of and measures the distance from to the nearest neighbor in . Note that this function is not is not symmetric and hence is not a true distance.

In particular, this filter uses the DanielssonDistanceMapImageFilter inside to compute distance map from all non-zero pixels in the second image. It then find the largest distance (in pixels) within the set of all non-zero pixels in the first image.

Use HausdorffDistanceImageFilter to compute the full Hausdorff distance.

This filter requires the largest possible region of the first image and the same corresponding region in the second image. It behaves as filter with two input and one output. Thus it can be inserted in a pipeline with other filters. The filter passes the first input through unmodified.

This filter is templated over the two input image type. It assume both image have the same number of dimensions.

void itk::DirectedHausdorffDistanceImageFilter< TInputImage1, TInputImage2 >::EnlargeOutputRequestedRegion DataObject   data [protected, virtual]
 

Give the process object a chance to indictate that it will produce more output than it was requested to produce. For example, many imaging filters must compute the entire output at once or can only produce output in complete slices. Such filters cannot handle smaller requested regions. These filters must provide an implementation of this method, setting the output requested region to the size they will produce. By default, a process object does not modify the size of the output requested region.

Reimplemented from itk::ProcessObject.

template<class TInputImage1, class TInputImage2>
void itk::DirectedHausdorffDistanceImageFilter< TInputImage1, TInputImage2 >::GenerateInputRequestedRegion   [protected, virtual]
 

What is the input requested region that is required to produce the output requested region? By default, the largest possible region is always required but this is overridden in many subclasses. For instance, for an image processing filter where an output pixel is a simple function of an input pixel, the input requested region will be set to the output requested region. For an image processing filter where an output pixel is a function of the pixels in a neighborhood of an input pixel, then the input requested region will need to be larger than the output requested region (to avoid introducing artificial boundary conditions). This function should never request an input region that is outside the the input largest possible region (i.e. implementations of this method should crop the input requested region at the boundaries of the input largest possible region).
