Catalano.Imaging.Tools.Granulometry

public class Granulometry
extends java.lang.Object

Calculate the granulometry function for a given image. In mathematical morphology, granulometry is an approach to compute a size distribution of grains in binary images, using a series of morphological opening operations. It was introduced by Georges Matheron in the 1960s, and is the basis for the characterization of the concept of size in mathematical morphology.

Constructor Detail

Granulometry

public Granulometry()

Initialize a new instance of the Granulometry class.

Granulometry

public Granulometry(int maxRadius)

Initialize a new instance of the Granulometry class.

Parameters:

maxRadius - Maximum radius.

Granulometry

public Granulometry(int minRadius,
                    int maxRadius)

Initialize a new instance of the Granulometry class.

Parameters:

minRadius - Minimum radius.

maxRadius - Maximum radius.

Granulometry

public Granulometry(int minRadius,
                    int maxRadius,
                    int steps)

Initialize a new instance of the Granulometry class.

Parameters:

minRadius - Minimum radius.

maxRadius - Maximum radius.

steps - Steps per radius.

Method Detail

getMinRadius

public int getMinRadius()

Get minimum radius.

Returns:

Radius.

setMinRadius

public void setMinRadius(int minRadius)

Set minimum radius.

Parameters:

minRadius - Radius.

getMaxRadius

public int getMaxRadius()

Get maximum radius.

Returns:

Radius.

setMaxRadius

public void setMaxRadius(int maxRadius)

Set maximum radius.

Parameters:

maxRadius - Radius.

getSteps

public int getSteps()

steps - Steps.

ProcessImage

public float[] ProcessImage(FastBitmap fastBitmap)
