ISO 12233 (slanted edge) spatial frequency response analysis.
[results, fitme, esf] = ieISO12233(barImage, deltaX, weight);
Slanted-edge and color mis-registration analysis.
barImage: The RGB image of the slanted bar
deltaX: The sensor sample spacing in millimeters
weight: The luminance weights; these are [0.3R + 0.6G + 0.1B] by
default.
fitme: The full linear fit to something
esf: Not sure
