I am trying to reproduce example imglib2-tutorials Example6c
https://github.com/imglib/imglib2-tutorials/blob/master/src/main/java/Example6c.java using the new net.imglib2.algorithm.fft2.FFT rather than the old deprecated net.imglib2.algorithm.fft.FourierTransform The original example code does: // compute fourier transform of the template final FourierTransform< FloatType, ComplexFloatType> fft = new FourierTransform< FloatType, ComplexFloatType>( template, new ComplexFloatType()); fft.process(); Img< ComplexFloatType> templateFFT = fft.getResult(); Which produces an image of size templateFFT minX=0 minY=0 maxX=40 maxY=79 My new code looks like this: ImgFactory<ComplexFloatType> fftImgFactory = null; try { fftImgFactory = template.factory().imgFactory(new ComplexFloatType()); } catch (IncompatibleTypeException ex) { fftImgFactory = null; } // compute fourier transform of the template Img< ComplexFloatType> templateFFT2 = FFT.realToComplex(template, fftImgFactory); Which produces an image of size templateFFT2 minX=0 minY=0 maxX=36 maxY=71 Also it looks like the image produced by the old FourierTransform and new FFT differ in that the results are shifted in X and Y. Can anyone help? In particular I want to achieve the image alignment functionality that is done in Example6c.java without using deprecated code.
