Detailed Description

class itk::AttributeMorphologyBaseImageFilter< TInputImage, TOutputImage, TAttribute, TFunction >

Morphological opening by attributes.

This is the base class for morphology attribute operations. Attribute openings remove blobs according to criteria such as area. When applied to grayscale images it has the effect of trimming peaks based on area while leaving the rest of the image unchanged. It is possible to use attributes besides area, but no others are implemented yet. This filter uses some dodgy coding practices - most notably copying the image data to a linear buffer to allow direct implementation of the published algorithm. It should therefore be quite a good candidate to carry out tests of itk iterator performance with randomish access patterns.

This filter is implemented using the method of Wilkinson, "A comparison of algorithms for Connected set openings and Closings", A. Meijster and M. H. Wilkinson, PAMI, vol 24, no. 4, April 2002. Attempts at implementing the method from ISMM 2000 are also included, but operation appears incorrect. Check the ifdefs if you are interested.
