Compute spatial frequency support for an optical image
fSupport = oiFrequencySupport(oi,units)
Various calculations, such as the OTF, require the range of spatial
frequencies in the optical image supported by the sampling density.
This routine, and the company sceneFrequencySupport, compute the
spatial frequency support and return it as an array.
The default units of fSupport are cycles/deg of visual angle. Other
options are cycles/distance (e.g., cycles/meter, cycles/mm,
cycles/microns).
Examples:
fSmm = oiFrequencySupport(oi,'mm'); % cycles/millimeter
fScpd = oiFrequencySupport(oi,'cycPerDeg');
fScpd = oiFrequencySupport(oi);
