Method Details

multiChannel

public static MeasurementProcessor.CustomMeasurement<BufferedImage,BufferedImage> multiChannel(String name,
 List<ColorTransforms.ColorTransform> transforms,
 Function<double[][],Double> function,
 Function<PathObject,ROI> roiFunction)

Create a new object measurement that requires multiple channels as input.

Parameters:

name - name of the measurement

transforms - transforms to extract the channels

function - function to calculate the measurement from the pixels

roiFunction - function to select a ROI from an object (generally the main ROI or nucleus)

Returns:

multiChannel

public static MeasurementProcessor.CustomMeasurement<BufferedImage,BufferedImage> multiChannel(String name,
 List<ColorTransforms.ColorTransform> transforms,
