Anamorphic Signature Identification Based on Correlative Specific Area of Restored and Segmented Image with Transformable Gridding
Ning Wang, Guoqiang Han · 2007
This paper proposes a method to identify the anamorphic signature.The signature is set on a transformable gridding.Moving the gridding in opposite direction with anamorphic direction, the anamorphic signature is restored.Meanwhile, the restored signature is segmented into equal-area sections by the gridding.The specific area is the ratio of strokes area to section area for each section.It is constant for every signature despite for the anamorphic signature.The correlation coefficient between identified and standard signature is calculated according to their specific areas.The high correlation coefficient expresses the high similarity between the identified and standard signature.
