A Distance-Based Technique for Non-Manhattan Layout Analysis
Layout analysis is a fundamental step in automatic document processing. Many different techniques have been proposed in literature to perform this task. These are broadly divided in two main categories according to the approach they follow: the top-down methods start by identifying the high level components of the page structure and then recursively split them until basic blocks are found. On the other hand, bottom-up approaches start with the smallest elements (e.g., the pixels in case of digitized document) and then recursively merge them into higher level components. A first limitation of such methods is that most of them are designed to deal only with digitized documents and hence are not applicable to the general case of native digital documents which are mainly diffused. Furthermore, top-down and most of bottom-up methods are able to process Manhattan layout documents only. In this work, we propose a general bottom-up strategy to tackle the layout analysis of (possibly) non-Manh...
