Class IqmOpACF

java.lang.Object

at.mug.iqm.api.operator.AbstractOperator

at.mug.iqm.img.bundle.op.IqmOpACF

All Implemented Interfaces:

IProgressEmitter, ICancelable, IOperator

public class IqmOpACF
extends AbstractOperator

This is the main image processing class There exist two approaches: A user defined JAI operator is just called or: The actual processing is implemented in this class

Since:

2012 11 This class calculates the Autocorrelation function ACF of an image using DFT FFT(ACF) = FFT(image) * (complex conjugate (FFT(image))
