Abstract
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 simultan eously detected several versions in the same scene, because each Scale fact or is codified in a different wavelength. Experimental results demonstrate the proposed technique and show the utility of the method. (C) 2000 Optical Society America.
