Layout Analysis for Handwritten Documents. A Probabilistic Machine Learning Approach
Lorenzo Quirós Díaz · 2022
Document Layout Analysis, applied to handwritten documents, aims to automatically obtain the intrinsic structure of a document. Its development as a research field spans from the character segmentation systems developed in the early 1960s to the complex systems designed nowadays, where the goal is to analyze high-level structures (lines of text, paragraphs, tables, etc) and the relationship between them. This thesis first defines the goal of Document Layout Analysis from a probabilistic perspective. Then, the complexity of the problem is reduced, to be handled by modern computing resources, into a set of well-known complementary subproblems. More precisely, three of the main subproblems of Document Layout Analysis are addressed following a probabilistic formulation, namely Baseline Detection, Region Segmentation and Reading Order Determination.
