Field Detail

template

public FImage template

The template image

Constructor Detail

FourierCorrelation

public FourierCorrelation(FImage template)

Construct the correlation operator with the given template

Parameters:

template - the template

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.

correlate

public static FImage correlate(FImage image,
                               FImage template,
                               boolean inplace)

Correlate an image with a kernel using an FFT.

Parameters:

image - The image

template - The template to correlate with the image

inplace - if true, then output overwrites the input, otherwise a new image is created.

Returns:

correlation map
