All Implemented Interfaces:

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

public class MaxFilter
extends Object
implements SinglebandImageProcessor<Float,FImage>

Max filter; replaces each pixel with the maximum of its neighbours. This is equivalent to greyscale morphological dilation.

Constructor Detail

MaxFilter

public MaxFilter(Set<Pixel> support)

Construct with the given support region for selecting pixels to take the median from. The support mask is a set of n relative x, y offsets from the pixel currently being processed, and can be created using the methods or constants in the FilterSupport class.

Parameters:

support - the support coordinates

Method Detail

processImage

public void processImage(FImage image)

Specified by:

processImage in interface ImageProcessor<FImage>

filter

public static void filter(FImage img,
                          int times)

Apply the filter some number of times to an image with the default 3x3 block support

Parameters:

img - the image

times - the number of times to apply the dilation
