During the last decades, the interest in preserving digitally historical documents have gained considerable attention. To exploit all the advantages and opportunities offered by the digitized documents, it's necessary to understand their contents. The first step toward that understanding is to determine the locations of the entities of the document, such as figures, titles, and captions, text, etc. This paper presents a new hybrid approach to analyze the structure of documents that is founded on morphological operators and connected components. The proposed method is divided into two stages, preprocessing, in which the quality of the document images is enhanced; and layout analysis, in which, we identify three types of layout. We also include a fragmentation process, in which we divide the page image into sections. Finally, We conducted the experiments on a dataset containing ancient historical newspapers.
