Query: LAREX - A semi-automatic open-source Tool for Layout Analysis and Region
  Extraction on Early Printed Books   A semi-automatic open-source tool for layout analysis on early printed books
is presented. LAREX uses a rule based connected components approach which is
very fast, easily comprehensible for the user and allows an intuitive manual
correction if necessary. The PageXML format is used to support integration into
existing OCR workflows. Evaluations showed that LAREX provides an efficient and
flexible way to segment pages of early printed books.
