Constructor Detail

Susan

public Susan()

Standart constructor with radius 2 and threshold 15

Susan

public Susan(int radius,
     int threshold)

Parameters:

radius - Radius in which the image is looked at

threshold - Threshold for difference in luminosity

Method Detail

supports

public EnumSet<Descriptor.Supports> supports()

Defines the capability of the algorithm.

Returns:

PlugInFilter, supports()

run

public void run(ij.process.ImageProcessor ip)

Description copied from interface: Descriptor

Start processing of this algorithm on the given image processor. Keep in mind that if the imageProcessor is changed, Supports.NoChanges must not be set. This is also the case even if only ImageProcessor.snapshot() is used.

getEdgemask

public ij.process.ByteProcessor getEdgemask()

Returns:

the edge mask with edges being marked with 255

getRadius

public int getRadius()

Returns:

Radius in which the image is investigated

setRadius

public void setRadius(int radius)

Parameters:

radius - Radius in which the image is investigated

getThreshold

public int getThreshold()

Returns:

Threshold for difference in luminosity

setThreshold

public void setThreshold(int threshold)

Parameters:

threshold - Threshold for difference in luminosity
