Class AdaptiveLocalThresholdContrast

java.lang.Object

org.openimaj.image.processing.threshold.AbstractLocalThreshold

org.openimaj.image.processing.threshold.AdaptiveLocalThresholdContrast

All Implemented Interfaces:

ImageProcessor<FImage>, Processor<FImage>, SinglebandImageProcessor<Float,FImage>

public class AdaptiveLocalThresholdContrast
extends AbstractLocalThreshold

Adaptive local thresholding using the local contrast. Pixels are set to 1 if they are closer to the local maximum rather than the local minimum.

Constructor Detail

AdaptiveLocalThresholdContrast

public AdaptiveLocalThresholdContrast(int size)

Construct the thresholding operator with the given patch size (assumed square)

Parameters:

size - size of the local image patch

AdaptiveLocalThresholdContrast

public AdaptiveLocalThresholdContrast(int size_x,
                                      int size_y)

Construct the thresholding operator with the given patch size

Parameters:

size_x - width of patch

size_y - height of patch

Method Detail

processImage

public void processImage(FImage image)

Description copied from interface: ImageProcessor

Process an image. Implementing classes must alter the image passed in-place or assign the output to the input using Image.internalAssign(Image).

Parameters:

image - The image to process in place.
