com.lightcrafts.media.jai.opimage.DFTOpImage

An OpImage implementing the forward and inverse discrete Fourier transform (DFT) operations as described in com.lightcrafts.mediax.jai.operator.DFTDescriptor and com.lightcrafts.mediax.jai.operator.IDFTDescriptor.

The DFT operation is implemented using a one-dimensional decimation in time fast Fourier transform (FFT) which is applied successively to the rows and the columns of the image. All image dimensions are enlarged to the next positive power of 2 greater than or equal to the respective dimension unless the dimension is unity in which case it is not modified. Source image values are padded with zeros when the dimension is smaller than the output power-of-2 dimension. @since EA3 @see com.lightcrafts.mediax.jai.UntiledOpImage @see com.lightcrafts.mediax.jai.operator.DFTDescriptor @see com.lightcrafts.mediax.jai.operator.IDFTDescriptor
