Base class for fast binary dilation and erosion.

BinaryMorphologyImageFilter is a base class for fast binary morphological operations. The implementation of this class and its subclasses are based on the papers:

L.Vincent "Morphological transformations of binary images with arbitrary structuring elements", and

N.Nikopoulos et al. "An efficient algorithm for 3d binary morphological transformations with 3d structuring elements for arbitrary size and shape". IEEE Transactions on Image Processing. Vol. 9. No. 3. 2000. pp. 283-286.

Gray scale images can be processed as binary images by selecting a "ForegroundValued" (which subclasses may alias as "DilateValue" or "ErodeValue"). Pixel not matching the foreground value are considered "background". This is useful in processing segmented images where all pixels in segment #1 have value 1 and pixels in segment #2 have value 2, etc. A particular "segment number" can be processed. ForegroundValue defaults to the maximum possible value of the PixelType.

The structuring element is assumed to be composed of binary values (zero or one). Only elements of the structuring element having values > 0 are candidates for affecting the center pixel. A reasonable choice of structuring element is itk::BinaryBallStructuringElement.

Description of the algorithm:

Let's consider the set of the ON elements of the input image as X.

Let's consider the structuring element as B = {B0, B1, ..., Bn}, where Bi denotes a connected component of B.

Let's consider bi, i in [0,n], an arbitrary point of Bi.

We use hence the next property in order to compute minkoswki addition ( which will be written (+) ):

X (+) B = ( Xb0 UNION Xb1 UNION ... Xbn ) UNION ( BORDER(X) (+) B ),

where Xbi is the set X translated with respect to vector bi :

Xbi ={ x + bi, x belongs to X }

where BORDER(X) is the extracted border of X ( 8 connectivity in 2D, 26 in 3D )

Our implementation for dilation is defined as:

X (+) SYM(B) = DILATION(X)_B

Where DILATION(X)_B is the dilation of set with structuring element B. Where SYM(B) is the symmetric of the structuring element relatively to its center.

This code was contributed by Jerome Schmid from the University of Strasbourg who provided a fast dilation implementation. Gaetan Lehmann from INRA de Jouy-en-Josas then provided a fast erosion implementaton based on Jerome's implementation. The common portions of these two implementations were then placed in this superclass.
