qupath.lib.images.servers.ColorTransforms

public class ColorTransforms
extends Object

Color transforms that may be used to extract single-channel images from BufferedImages. These are JSON-serializable, and therefore can be used with pixel classifiers.

Method Details

createChannelExtractor

public static ColorTransforms.ColorTransform createChannelExtractor(int channel)

Create ColorTransform to extract a channel based on its number (0-based index, although result of ColorTransforms.ColorTransform.getName() is 1-based).

Parameters:

channel -

Returns:

createChannelExtractor

public static ColorTransforms.ColorTransform createChannelExtractor(String channelName)

Create ColorTransform to extract a channel based on its name.

Parameters:

channelName -

Returns:

createMeanChannelTransform

public static ColorTransforms.ColorTransform createMeanChannelTransform()
