Identity Document and banknote security forensics: a survey

no code implementations20 Oct 2019 Albert Berenguel Centeno, Oriol Ramos Terrades, Josep Lladós Canet, Cristina Cañero Morales

Aiming to detect these counterfeits, the present survey covers a wide range of anti-counterfeiting security features, categorizing them into three components: security substrate, security inks and security printing.

A probabilistic framework for handwritten text line segmentation

no code implementations7 May 2018 Francisco Cruz, Oriol Ramos Terrades

We successfully combine Expectation-Maximization algorithm and variational approaches for parameter learning and computing inference on Markov random felds.
