public class AlgorithmMorphologicalFilter
extends AlgorithmBase

Performs morphological filtering on black and white images. This is a shading correction routine, that is, it corrects for non-uniform illumination and non-uniform camera sensitivity. A morphological filtered pixel = the original pixel - the morphological smoothed pixel + a constant to restore the original average image brightness. A morphological smoothed pixel is given by the min(max(max(min(original pixel)))), where the sizes[] array contains the dimensions of the region examined for the minimum and the maximum.

Constructor Detail

AlgorithmMorphologicalFilter

public AlgorithmMorphologicalFilter(ModelImage srcImg,
                                    int[] sizes,
                                    boolean maskFlag,
                                    boolean img25D)

Constructs a Morphological filter object.

Parameters:

srcImg - source image model

sizes - Filter size in each dimension

maskFlag - Flag that indicates that the Morphological filter will be calculated for the whole image if equal to true

img25D - Flag, if true, indicates that each slice of the 3D volume should be processed independently. 2D images disregard this flag.

AlgorithmMorphologicalFilter

public AlgorithmMorphologicalFilter(ModelImage destImg,
                                    ModelImage srcImg,
                                    int[] sizes,
                                    boolean maskFlag,
                                    boolean img25D)

Constructs a Morphological filter object.

Parameters:

destImg - image model where result image is to stored

srcImg - source image model

sizes - Filter size in each dimension

maskFlag - Flag that indicates that the Morphological filter will be calculated for the whole image if equal to true

img25D - Flag, if true, indicates that each slice of the 3D volume should be processed independently. 2D images disregard this flag.
