Class SumBoxFilter

java.lang.Object

org.openimaj.image.processing.convolution.SumBoxFilter

All Implemented Interfaces:

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

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

A rectangular summing convolution operator (often known as a unnormalized Box filter). For efficiency, this is implemented using a SummedAreaTable rather than through an actual convolution.

Constructor Detail

SumBoxFilter

public SumBoxFilter(int width,
                    int height)

Construct the averaging operator with a kernel of the given dimensions.

Parameters:

width - width of the kernel

height - height of the kernel

SumBoxFilter

public SumBoxFilter(int dim)

Construct the averaging operator with a square kernel of the given dimension.

Parameters:

dim - The width and height of the box

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).

Specified by:

processImage in interface ImageProcessor<FImage>

Parameters:

image - The image to process in place.
