Detailed Description

A filter that reduces the number of points of contours represented by a mitk::Surface.

The type of the reduction can be set via SetReductionType. The two ways provided by this filter is the

NTH_POINT Algorithm which reduces the contours according to a certain stepsize
DOUGLAS_PEUCKER Algorithm which incorpates an error tolerance into the reduction.

Stepsize and error tolerance can be set via SetStepSize and SetTolerance.

Additional if more than one input contour is provided this filter tries detect contours which occur just because of an intersection. These intersection contours are eliminated. In oder to ensure a correct elimination the min and max spacing of the original image must be provided.

The output is a mitk::Surface.
