A method for comparing first and second digital representations of an image, the method comprising the steps of: for each individual translation from among a plurality of translations from the first digital representation to the second digital representation: for each individual image location from among a plurality of image locations within a comparison entity within the first digital representation, determining a binary legitimacy value of the individual translation for the individual image location by comparing the individual image location to a location in the second digital representation defined by operating the individual translation on the individual image location; and combining the binary legitimacy values of image locations within the comparison entity, thereby to generate a comparison entity legitimacy value determining whether the individual translation is legitimate for the comparison entity; and announcing a defect for the comparison entity if none of the plurality of translations are legitimate therefor.

[ We claim:] [1.] A method for aligning first and second digital representations of an image, the method comprising, for each individual large location from among a plurality of relatively large locations covering the first digital representation:for each individual translation from among a plurality of translations from the first digital representation to the second digital representation:for each individual small location from among a multiplicity of relatively small locations included in the individual large location, determining a binary legitimacy value of the individual translation for the individual small location, the binary legitimacy value comprising:a legitimacy-indicating value if the translation translates the small location onto a small location of similar appearance within the second digital representation: anda non-legitimacy-indicating value if the translation translates the small location onto a small location of dissimilar appearance within the second digital representation;combining the binary legitimacy values of the small locations included in the individual large location into a success score representing the success of the individual translation in translating the individual large location; andimproving the alignment of the first and second digital representations by operating an individual translation on the individual large location, wherein the individual translation is selected from the plurality of translations on the basis of the success score of the individual translation for the individual large location,wherein success of a translation in translating a large location is an increasing function of the number of small locations within the large locations whose binary legitimacy value comprises said legitimacy-indicating value.
