Class DFTConvolveDescriptor

java.lang.Object
javax.media.jai.OperationDescriptorImpl
com.bc.ceres.jai.operator.DFTConvolveDescriptor
All Implemented Interfaces:
Serializable, javax.media.jai.OperationDescriptor, javax.media.jai.RegistryElementDescriptor
public class DFTConvolveDescriptor extends javax.media.jai.OperationDescriptorImpl
An OperationDescriptor describing the "DFTConvolve" operation.

This operation behaves as the JAI standard "Convolve" operation but uses a Fast Fourier Transformation for the convolution.

    • create

      public static javax.media.jai.RenderedOp create(RenderedImage source0, javax.media.jai.KernelJAI kernel, RenderedImage kernelFT, RenderingHints hints)
      Performs kernel-based convolution on an image.

      Creates a ParameterBlockJAI from all supplied arguments except hints and invokes JAI.create(String, java.awt.image.renderable.ParameterBlock, java.awt.RenderingHints).

      Parameters:
      source0 - RenderedImage source 0.
      kernel - The convolution kernel.
      kernelFT - The Fourier-transformed convolution kernel image, may be null.
      hints - The RenderingHints to use. May be null.
      Returns:
      The RenderedOp destination.
      Throws:
      IllegalArgumentException - if source0 is null or if if kernel is null.
