A previous method of obtaining scale-invariance detection with
white-light illumination has been improved on. We were able to
detect different scaled versions of the target up to a magnification
factor equal to 2. We simultaneously detected several versions in
the same scene, because each scale factor is codified in a different
wavelength. Experimental results demonstrate the proposed technique
and show the utility of the method.
