public class AdjoiningPixelDetector

extends Operation

The AdjoiningPixelDetector is a class to deblend pixels of the image into some sets of adjoining pixels whose value is greater than the specified threshold.

Note that the value of the image is changed after the operation.

Field Summary

protected MonoImage	image The image where to deblend into some sets of adjoining pixels.
protected java.util.Vector	list The list of adjoining pixels.
protected double	minimum_peak The minimum peak value to detect a set of adjoining pixels.
protected double	threshold The threshold.

Constructor Detail

AdjoiningPixelDetector

public AdjoiningPixelDetector(MonoImage image)

Constructs a AdjoiningPixelDetector with a image object where to deblend into some sets of adjoining pixels.

Parameters:

image - the image where to deblend.

Method Detail

setThreshold

public void setThreshold(double new_threshold)

Sets the threshold.

Parameters:

new_threshold - the threshold value.

setMinimumPeakValue

public void setMinimumPeakValue(double new_value)

Sets the minimum peak value to detect a set of adjoining pixels.

Parameters:

new_value - the minimum peak value.

getAdjoiningPixelList

public java.util.Vector getAdjoiningPixelList()

Gets the list of adjoining pixels.

Returns:

the list of adjoining pixels.

ready

public boolean ready()

Returns true if the operation is ready to start.

Overrides:

ready in class Operation

Returns:

true if the operation is ready to start.

operate

public void operate()
             throws java.lang.Exception

Operates.

Overrides:

operate in class Operation

java.lang.Exception - if an error occurs.

detectAdjoiningPixel

private AdjoiningPixel detectAdjoiningPixel(int x,
                                            int y)

Detects adjoining pixels around the specified position. The pixel values in the image is changed by this process.

Parameters:

x - the x position.

y - the y position.

Returns:

the adjoining pixels around the specified position.
