Class MeasurementProcessor

java.lang.Object

qupath.lib.experimental.pixels.MeasurementProcessor

public class MeasurementProcessor
extends Object

Create PixelProcessor instances that make measurements from objects.

Important! This class is intended to simplify making measurements where all pixel values can fit into a single double array. It is not suitable for large images or tiling.

It is also not very efficient if the same channel is used multiple times, since the channel will be extracted each time.

Method Details

createProcessor

public static <S,
T>
Processor<S,T,Map<String,? extends Number>> createProcessor(MeasurementProcessor.CustomMeasurement<S,T>... measurement)

Create a processor that can make custom measurements for an image object.

Note that it assumes that all pixels can fit in memory, therefore it is not suitable for large images or tiling.

Type Parameters:

S -

T -

Parameters:

measurement -

Returns:

createProcessor

public static <S,
T>
Processor<S,T,Map<String,? extends Number>> createProcessor(Collection<? extends MeasurementProcessor.CustomMeasurement<S,T>> measurements)

Create a processor that can make custom measurements for an image object.

Note that it assumes that all pixels can fit in memory, therefore it is not suitable for large images or tiling.

Type Parameters:

S -

T -

Parameters:

measurements -

Returns:

builder

public static PixelProcessor.Builder<BufferedImage,BufferedImage,Map<String,? extends Number>> builder(Collection<? extends MeasurementProcessor.CustomMeasurement<BufferedImage,BufferedImage>> measurements)

Create a new builder for a PixelProcessor that can make custom measurements for an image object. The builder is ready to use, but can also be further customized if required (e.g. to set the resolution).

Parameters:

measurements -

Returns:
