I have a real image at 1 km resolution that I want to resample at 0.125 km
resolution while adding structure or details at the smaller scales (1 to .125
km). The goal is to add "realistic" if artificial small scale details to the
image. The scene would then be processed by a sensor simulation model which
includes a point spread function larger than 0.12 km.
Simple interpolation to higher resolution would not add any small scale
structure. One approach would be to take a 2-D fourier transform of the
image to get the power spectrum and phase, then extend these somehow to
smaller length scales. Does anyone know of a dicussion of this approach? What
would be the appropriate way to extend the power and phase?
I am also vaguely aware that fractals might be applied to this problem.
Again, any pointers to a discussion?
Thanks,
