Method Details

newInstance

public static SharpenFilter newInstance(org.apache.commons.cli.CommandLine commandLine,
 ReadableImage image)
                                 throws InvalidArgumentException

Creates a new SharpenFilter using the supplied command line arguments.

Parameters:

commandLine - the command line from which a program is invoked.

image - the image to which this filter is designed to apply.

Returns:

a new SharpenFilter.

Throws:

InvalidArgumentException - if the filter cannot be created from the arguments.

new2DInstance

public static SharpenFilter new2DInstance(ReadableImage image,
 int kernelSize)

Creates a new 2-D SharpenFilter suitable for filtering the supplied image.

Parameters:

image - the image to which this filter is designed to apply. The image pixel size is used to scale the kernel weights.

kernelSize - the (odd) kernel size for the filter.

Returns:

new 2-D SharpenFilter.

new2DInstance

public static SharpenFilter new2DInstance(float pixelXSize,
 float pixelYSize,
 int kernelSize)

Creates a new 2-D SharpenFilter suitable for filtering an image with the given pixel sizes.

Parameters:

pixelXSize - the pixel width.

pixelYSize - the pixel height.

kernelSize - the (odd) kernel size for the filter.

Returns:

new 2-D SharpenFilter.

new3DInstance

public static SharpenFilter new3DInstance(ReadableImage image,
 int kernelSize)
                                   throws InvalidImageException

Creates a new 3-D SharpenFilter suitable for sharpening the supplied image.

Parameters:

image - the image to which this filter is designed to apply. The image pixel sizes are used to determine the kernel weights.

kernelSize - the (odd) kernel size for the filter.

Returns:

new 3-D SharpenFilter.

Throws:

InvalidImageException - if the supplied image is invalid.

new3DInstance

public static SharpenFilter new3DInstance(float pixelXSize,
 float pixelYSize,
 float pixelZSize,
 int kernelSize)

Creates a new 3-D SharpenFilter suitable for sharpening an image.

Parameters:

pixelXSize - the image horizontal pixel size used to determine the kernel weights.

pixelYSize - the image vertical pixel size used to determine the kernel weights.

pixelZSize - the image slice thickness used to determine the kernel weights.

kernelSize - the (odd) kernel size for the filter.

Returns:

new 3-D SharpenFilter.

getOptionName

public static String getOptionName()

Returns the name of this type of filter when specifying it in program optional arguments.

Returns:

the name of the filter for selection in program arguments.

getSpecifierPanel

public static SpatialFilter.SpecifierPanel getSpecifierPanel(String preferencesNodeName)

Returns a SpatialFilter.SpecifierPanel that can be used to set the parameters for a SharpenFilter.

Parameters:

preferencesNodeName - the preferences node name from which the initial settings will be taken.

Returns:

a SpatialFilter.SpecifierPanel to set the parameters for this type of filter.

getName

public static String getName()

Returns the human-readable name of this filter.

Returns:

the human-readable name of this filter.

main

public static void main(String[] args)

Runs a self-test of this class.

Parameters:

args - the program aguments (ignored).
