Handwritten Signature SDK was developed for a thesis in computer science at UniSa.
This project borns because of need to use a fairly complete and free SDK to work on handwritten signature.
SDK is based on signature-verification project, that implements DTW and ER2 algorithms, which I added other features read on scientific articles, as you can see:
- Dynamic time warping with Sakoe-Chiba band.
- Extended Regression in 2 dimensions.
- Signature sampling by points coords and not on an image.
- Directional Hash: generate an hash from signature according to X and Y movements.
- Signature rotation by barycenter: this technique is to be test more, but it works if signatures are similar.
- Methods to extract: velocity, internal and external angles and critical points.
