Document Layout Analysis (DLA) is a key preprocessing stage for optical character recognition (OCR). It locates and defines text and non-text regions of a document image. Arabic DLA is less addressed compared to other languages due to the lack of appropriate publicly available research datasets.A full pipeline of DLA procedure is composed of several stages: Input document Preprocessing, Document Physical layout Analysis (PLA), Document Logical Layout Analysis (LLA), and document analysis output representation. In this thesis, CCs geometric features are used to represent the Arabic document images These CCs features are classified by means of Support Vector Machines (SVM) and Random Forests (RF) classifiers into text and non-text components to perform PLA for scanned Arabic book pages. Experiments on BCE-v1, and other researcher's datasets showed remarkable performance of both the SVM and RF based solutions. Comparing to other classical and state-of-the-art systems showed much strength to the proposed system and promise further application to wider problem domains
