Problems solved by technology

[0003] Its disadvantages are: there is no professional verification equipment and verification method to objectively identify and compare the original signature and the verification signature, and only rely on personal experience to observe and judge, which is easily interfered by subjective factors and the verification effect is poor

Embodiment Construction

[0048] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0049] As shown in Figure 1 and Figure 8: a signature identification method includes the following steps:

[0050] Step 1. Obtain the envelope curves of the original signature and the verified signature respectively:

[0051] Use a scanning device to read the original signature and verify the signature pattern respectively, as shown in Figure 2.1, the original input signature image, the scanning device sends the pattern information to the computer, and the computer uses the expansion operator to thicken the strokes of the signature handwriting to make the signature handwriting The strokes are connected, as shown in Figure 2.2, to form a whole, and then use the contour tracking operator to obtain the envelope curves of the original signature and the verification signature as shown in Figure 2.3;

[0052]Step 2. Extract the curvature o...

Abstract

A method for identifying signature includes obtaining envelope curves of original signature and verification signature, separately picking up envelope curve curvity of original and verification signatures as identifications of signature, carrying out regularization-corresponding of envelope curve curvity on original signature to envelope curve curvity on verification signature and utilizing weighted Eustachian distance grader to identify envelope curve curvities of original and verification signatures.

Description

technical field [0001] The invention belongs to a method for personal identity authentication and recognition, in particular to a signature recognition method for verifying personal notes. Background technique [0002] At present, in the personal identity authentication and identification technology, personal signature notes are used for identification, but this identification can only stay on the basis of human observation, that is, the original signature written by the party in advance as the verification credential, when the signature is required to identify the party When identifying the identity, write out the verification signature, and others rely on personal experience to observe and compare whether the original signature and the verification signature are consistent, so as to judge whether the identity of the party is true. [0003] Its disadvantages are: there is no professional verification equipment and verification method to objectively identify and compare the ...
