In the process of handwritten signature recognition, preliminary processing of the signature is an important step before identifying informative features. The signatures of one person always have some differences, in addition, they can be different colors, different sizes and orientations. Once signatures are digitized, their images may contain some noise. The purpose of preliminary processing of a signature image is to obtain the most invariant representation of a digital image of a person’s signature, which will allow him to be identified or to establish that the signature is forged.
