Method Details

getTypeAdapterFactory

public static TypeAdapterFactory getTypeAdapterFactory()

Get the TypeAdapterFactory default used for PixelClassifier objects. This is intended for internal use by QuPath, and should be registered with GsonTools.

Returns:

readClassifier

public static PixelClassifier readClassifier(Path path)
                                      throws IOException

Read a standard pixel classifier from a file.

Parameters:

path - the file containing the classifier

Returns:

Throws:

IOException

writeClassifier

public static void writeClassifier(PixelClassifier classifier,
 Path path)
                            throws IOException

Write a pixel classifier to a file.

Parameters:

classifier -

path -

Throws:

IOException

createClassifier

public static PixelClassifier createClassifier(ImageDataOp op,
 PixelCalibration inputResolution,
 Map<Integer,PathClass> classifications)

Convert an ImageDataOp into a simple classifier by adding an interpretation to the output labels.

Parameters:

inputResolution -

classifications -

Returns:

createClassifier

public static PixelClassifier createClassifier(ImageDataOp op,
 PixelClassifierMetadata metadata)

Convert an ImageDataOp into a simple classifier.

Parameters:

op -

metadata -

Returns:

createClassifier

public static PixelClassifier createClassifier(OpenCVClassifiers.OpenCVStatModel statModel,
 ImageDataOp calculator,
 PixelClassifierMetadata metadata,
 boolean do8Bit)

Create a PixelClassifier based on an OpenCV StatModel and feature calculator.

Parameters:

Returns:

createThresholdClassifier

public static PixelClassifier createThresholdClassifier(PixelCalibration inputResolution,
 int channel,
 double threshold,
 PathClass below,
 PathClass aboveEquals)

Create a new PixelClassifier that applies a threshold to one channel of an image.

Parameters:

inputResolution - resolution at which the threshold should be applied

channel - the channel to threshold (zero-based)

threshold - the threshold value to apply

below - the classification for pixels below the threshold (must not be null)

aboveEquals - the classification for pixels greater than or equal to the threshold (must not be null)

Returns:

the pixel classifier

createThresholdClassifier

public static PixelClassifier createThresholdClassifier(PixelCalibration inputResolution,
 Map<Integer,? extends Number> thresholds,
 PathClass below,
 PathClass aboveEquals)

Create a new PixelClassifier that applies a threshold to one or more channels of an image.

Parameters:

inputResolution - resolution at which the threshold should be applied

thresholds - map between channel numbers (zero-based) and thresholds

below - the classification for pixels whose values are below the threshold in any channel

aboveEquals - the classification for pixels whose values are greater than or equal to the threshold in all channels

Returns:

the pixel classifier
