Layout Analysis of Document Images
Nina S. T. Hirata · 2023
In order to extract information of interest from document images, their content must be recognized. To that end, layout analysis is an important step. In layout analysis one is concerned in finding page components such as text blocks, tables, formulas, diagrams, and determining their logical role. That could enable building of efficient representation of document content, with application possibilities such as determining the right reading order, establishing relationships between page components, or improving indexing in general. In this work, we revisit the layout analysis problem reviewing how it is being impacted by advances in the field of machine learning. Then, we conclude pointing some future works.
