abstract = "A very important research topic nowadays is the Automatic License
Plate Recognition (ALPC). This task consists in locating and
identifying an on-track vehicle automatically. This task can be
divided into the following subtasks: vehicle detection, license
plate detection, characters segmentation and character
recognition. This work proposes a new technique to perform
character segmentation, which is considered solved in the
literature, but in practice is a bottleneck for achieving a robust
ALPC system. Our approach is a learning-based technique that uses
a regression method known as Partial Least Squares to find the
best points where the segmentation should be done between the
characters. We perform experiments using a dataset composed of
2,000 license plates and three baselines to compare them with the
results obtained by the proposed approach. In addition, we
evaluate the usage of the PLS with five feature descriptors and
our results show that our method is able to achieve a result up to
46.5% of accuracy, evaluated by the Jaccard measure.",
