Siamese Signature Verificator

Deep Siamese Inception Neural Network for Off-Line Signature Verification

This repository presents a Siamese Neural Networks to help solving the off-line signature verification problem against random forgeries.

Our solution is writer-independent, and it can be used on new signers without any additional training.

For example, our solution can verify that the three first signtures belong to one signer, and the other two signtures belong to other signers.

We tested our approach on the SigComp11 dataset and achieved 4% of ERR in verification which demonstrates the generalization capabilities of our proposal. However, this is a preliminary version of our software. If you want our best version write us to


pip install -r requirements.txt


Test the system working

Using this link you can test the system working. To do that, first you have to create two PNG images with the signatures to be compared, or download from out sample directory.
