Is there any code or algorithm for signature recognition?

Question

My users draw their signature in my application using touch events and I convert it to a bitmap. I want to extract unique specifications of each signature and compare it by its specifications stored in the main server.

How can I do that?

What is the main and enterprise algorithm for extracting unique features of a signature?

Thanks in advance,

Answer 1

I think you are looking for feature extraction techniques. You can use the SIFT (Scale-Invariant Feature Transform). This algorithm allows you to compare stored features of an original signature to copies and identify a match with a high level of accuracy, even in the cases that the sample is scaled or rotated.

You can use also OpenCV with SIFT. You should check this source to know more.

Study Open Cv Machine Learning for more details. 

Hope this answer helps.
