Hi! I have developed Fourier analysis on the projective group well
adapted to perspective image transformations. Projective Fourier
transform (PFT) has the classical Fourier transform form in log-polar
coordinates, therefore computable in these coordinates by FFT. It seems
that it is the right computational framework for foveated image
processing. I look for someone who knows practical image processing and
want to work with me (for publications, or conditions open for
discussion) to implement PFT for real images. Regards.
