ABSTRACT:
An adjustment method of a machine-readable form model and a filled form scanned image thereof in the presence of distortion comprising model form free of distortion, image form, containing distortion, obtained by optical input device from paper media. One embodiment of the method comprises the steps of assigning of one of the forms as changeable, marking on the form regions containing distortion, computing the consolidated distortion correction factor of the spatial parameters for the said changeable form, parameters correction on the base of the said consolidated factor. Another embodiment of the method setting the correspondence between identical objects of image form and model form is followed by steps of computing distortion correction factors of the spatial parameters for each object of selected level, spatial parameters correction of the changeable form, on the base of the said factors, affecting objects of the same and lower identification reliability levels.
