Resumo(s)
Image recognition algorithms are used to extract information from digitized images
automatically. Systems designed to convert paper documents into meaningful vectorial representations
are numerous nowadays, and have been constantly improved over the two
last decades. However, none of these systems seems to be able to provide satisfying results
when it comes to convert complex documents such as technical drawings, usually semantic
of the problem is not considered and post-processing costs remain high. This dissertation
presents a set of techniques that greatly simplifies the automatic extraction of cadastral
entities from the portuguese cadastral maps. The validity of the approach is illustrated
designing a prototype system, joining all recognition algorithms and validating all information.
