Detailed Description

This filter computes the signed distance map of the input image as an approximation with pixel accuracy to the Euclidean distance.

This class is parameterized over the type of the input image and the type of the output image.

For purposes of evaluating the signed distance map, the input is assumed to be binary composed of pixels with value 0 and non-zero.

The inside is considered as having negative distances. Outside is treated as having positive distances. To change the convention, use the InsideIsPositive(bool) function.

As a convention, the distance is evaluated from the boundary of the ON pixels.

The filter returns

A signed distance map with the approximation to the euclidean distance.

A voronoi partition. (See itkDanielssonDistanceMapImageFilter)

A vector map containing the component of the vector relating the current pixel with the closest point of the closest object to this pixel. Given that the components of the distance are computed in "pixels", the vector is represented by an itk::Offset . That is, physical coordinates are not used. (See itkDanielssonDistanceMapImageFilter)

This filter internally uses the DanielssonDistanceMap filter. This filter is N-dimensional.

See also: itkDanielssonDistanceMapImageFilter; itk::simple::SignedDanielssonDistanceMap for the procedural interface; itk::SignedDanielssonDistanceMapImageFilter for the Doxygen on the original ITK class.

Get Voronoi Map This map shows for each pixel what object is closest to it. Each object should be labeled by a number (larger than 0), so the map has a value for each pixel corresponding to the label of the closest object.

This is a measurement. Its value is updated in the Execute methods, so the value will only be valid after an execution.
