abstract = "The main objective is to present an off-line signature
verification system. It is basically divided into three parts. The
first demonstrates a pre-processing process, a segmentation
process and a feature extraction process, in which the main aim is
to obtain the maximum performance quality of the process of
verification of random falsifications, in the false acceptance and
false rejection concept. The second presents a learning process
based on HMM, where the aim is obtaining the best model. That is,
one that is capable of representing each writer's signature,
absorbing yet at the same time discriminating, at most the
intrapersonal and interpersonal variation. The third presents a
signature verification process that uses the models generated by
the learning process without using any prior knowledge of test
data, in other words, using an automatic derivation process of the
decision thresholds.",
