well-defined five steps. But there is no agreement in what are the right tools and
strategies for image acquisition and processing. Each of the technological options
presented have their particular response. However, there is an emergent need to
develop such methodologies in order to meet a great ongoing demand and cover all
the requirements and restrictions of existing procedures due to the specificity of
each product, also aiming to standardize these new technologies.
