Historical document analysis based on word matching

Ankara : The Department of Computer Engineering and the Institute of Engineering and Science of Bilkent University, 2011.Thesis (Master's) -- Bilkent University, 2011.Includes bibliographical references leaves 67-76.Historical documents constitute a heritage which should be preserved and providing automatic retrieval and indexing scheme for these archives would be beneficial for researchers from several disciplines and countries. Unfortunately, applying ordinary Optical Character Recognition (OCR) techniques on these documents is nearly impossible, since these documents are degraded and deformed. Recently, word matching methods are proposed to access these documents. In this thesis, two historical document analysis problems, word segmentation in historical documents and Islamic pattern matching in kufic images are tackled based on word matching. In the first task, a cross document word matching based approach is proposed to segment historical documents into words. A version of a document, in which word segmentation is easy, is used as a source data set and another version in a different writing style, which is more difficult to segment into words, is used as a target data set. The source data set is segmented into words by a simple method and extracted words are used as queries to be spotted in the target data set. Experiments on an Ottoman data set show that cross document word matching is a promising method to segment historical documents into words. In the second task, firstly lines are extracted and sub-patterns are automatically detected in the images. Then sub-patterns are matched based on a line representation in two ways: by their chain code representation and by their shape contexts. Promising results are obtained for finding the instances of a query pattern and for fully automatic detection of repeating patterns on a square kufic image collection.Arifoğlu, DamlaM.S

Segmentation based Ottoman text and matching based Kufic image analysis

Ankara : The Department of Computer Engineering and the Graduate School of Engineering and Science of Bilkent University, 2013.Thesis (Master's) -- Bilkent University, 2013.Includes bibliographical references leaves 80-88.Large archives of historical documents attract many researchers from all around the world. The increasing demand to access those archives makes automatic retrieval and recognition of historical documents crucial. Ottoman archives are one of the largest collections of historical documents. Although Ottoman is not a currently spoken language, many researchers from all around the world are interested in accessing the archived material. This thesis proposes two Ottoman document analysis studies; first one is a crucial pre-processing task for retrieval and recognition which is segmentation of documents. Second one is a more specific retrieval and recognition problem which aims matching Islamic patterns is Kufic images. For the first segmentation task, layout, line and word segmentation is studied. Layout segmentation is obtained via Log-Gabor filtering. Four different algorithms are proposed for line segmentation and finally a simple morphological method is preferred for word segmentation. Datasets are constructed with documents from both Ottoman and other languages (English, Greek and Bangla) to test the script-independency of the methods. Experiments show that our segmentation steps give satisfactory results. The second task aims to detect Islamic patterns in Kufic images. The sub-patterns are considered as basic units and matching is used for the analysis. Graphs are preferred to represent subpatterns where graph and sub-graph isomorphism are used for matching them. Kufic images are analyzed in three different ways. Given a query pattern, all the instances of the query can be found through retrieval. Going further, through known patterns images can be automatically labeled in the entire dataset. Finally, patterns that repeat inside an image can be automatically discovered. As there is no existing Kufic dataset, a new one is constructed by collecting images from the Internet and promising results are obtained on this dataset.Adıgüzel, HandeM.S

101 Obras maestras: ciencia y arte en los museos y bibliotecas de Madrid

[EN] More than 365 days, more than 30 institutions, more than 50 authors and 101 (or more) works are the numbers which brings together this project. The title 101 Masterworks: Science and Art in the Museums and Libraries of Madrid gathers a collection of pieces with different chronologies, techniques, materials and purposes. Also varied are their locations: from Alcalá de Henares to San Lorenzo del Escorial, as well as Atocha, el Prado, Recoletos, the Complutense University campus, and an endless number of spaces within the city and the Community of Madrid. Despite the apparent disparateness of these works, they all share a common singularity: being a representative piece in the history of science and the history of art which, despite being recognised as both distant and different, developed hand in hand over the centuries.[ES] Más de 365 días, más de 30 instituciones, más de 50 autores y 101 obras (o más) son cifras cuya suma da como resultado este proyecto. Bajo el título 101 obras maestras: ciencia y arte en los museos y bibliotecas de Madrid se reúnen un conjunto de piezas de diversas cronologías, técnicas, materiales y finalidades. Variadas son también sus ubicaciones: de Alcalá de Henares a San Lorenzo de El Escorial, pasando por Atocha, el Prado, Recoletos, el campus universitario de la Complutense, y un sinfín de otras localizaciones en la ciudad y Comunidad de Madrid. A pesar de esta aparente amalgama, todas ellas aúnan la peculiaridad de ser representativas de las historias de la ciencia y del arte, las cuales, aunque en la actualidad son reconocidas como distantes y dispares entre sí, a lo largo de los siglos caminaron de la mano.La realización de éste proyecto ha sido posible gracias a la financiación de la Fundación Española para la Ciencia y la Tecnología en su Convocatoria de Ayudas del Programa de Cultura Científica y de la Innovación 2012Peer reviewe

Análisis de motivos decorativos de tejidos y revestimientos cerámicos en el entorno de la visión artificial. Aplicación a la reconstrucción de motivos históricos y al diseño

El objetivo de esta tesis es la contribución a la creación, e implementación en herramientas informáticas, de una metodología aplicable para el análisis y edición de imágenes procedentes del campo de los diseños cerámicos y textiles, y por extensión, de todas aquellas imágenes que siguen un patrón repetitivo y que, por tanto, se ajustan a la Teoría de Grupos de Simetría. Para ello, se ha definido una metodología de análisis dividida en etapas, en la que se va aumentando gradualmente el nivel de la información manejada, desde los píxeles de la imagen inicial, pasando por los objetos (formas o unidades básicas perceptúales) y los motivos (agrupaciones de objetos realizadas con criterios perceptúales) hasta llegar a la estructura del patrón, es decir, las distintas transformaciones geométricas que relacionan los elementos (objetos y motivos) que lo forman. La información estructural obtenida es utilizada con fines diversos: la clasificación de las imágenes según el Grupo de Simetría del Plano del patrón, la reconstrucción de las imágenes aprovechando el conocimiento de qué partes están relacionadas por la estructura, y por último, la edición de patrones, tanto a nivel de formas y motivos, como de estructura, permitiendo realizar cambios estructurales con facilidad, con lo que se generan familias de patrones a partir de uno analizado. Las herramientas desarrolladas han sido probadas con un amplio conjunto de imágenes de patrones de procedencias muy diversas, destacando el estudio de los alicatados de la Alhambra de Granada y del Alcázar de Sevilla, así como de textiles y, ampliando los objetivos iniciales, a diversos elementos del entorno urbano.Albert Gil, FE.
