Video-Based Tracking of Physical Documents on a Desk
FACULTY OF ENGINEERING Department of Electronics and Informatics Video-based Tracking of Physical Documents on a Desk Graduation thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Applied Sciences and Engineering: Applied Computer Science Sone Nsime Ngole Promoter: Prof. Dr. Beat Signer Advisor: Dr. Bruno Dumas JANUARY 2014 FACULTEIT INGENIEURSWETENSCHAPPEN Vakgroep Elektronica en Informatica Video-based Tracking of Physical Documents on a Desk Afstudeer eindwerk ingediend in gedeeltelijke vervulling van de eisen voor het behalen van de graad Master of Science in de Ingenieurswetenschappen: Toegepaste Computerwetenschappen Sone Nsime Ngole Promoter: Prof. Dr. Beat Signer Advisors: Dr. Bruno Dumas JANUARI 2014 Abstract Currently, physical and digital documents tend to stay in their world, without any direct relationship linking them. How- ever, a lot of physical documents are printed from digital doc- uments and conversely, digital documents can be scanned ver- sions of printed papers. Furthermore, the organization of piles of physical documents on a desk hints at shared semantic fea- tures between a set of documents. This thesis explores an ap- proach to link or re-link physical documents with their digital counterpart. This integration will be done by designing a sys- tem that uses an overhead digital camera to recognize, identify, localize and track paper documents on the physical desk space in real time (or offline by means of a pre-recorded video stream) and automatically matching them against an image database of electronic documents. The system locates each paper docu- ment that is present on the desk and reconstructs a complete configuration of documents on the desk at each instant in time. -
Diplomová Práce Inteligentní Vyhledávání Dokumentů
Západočeská univerzita v Plzni Fakulta aplikovaných věd Katedra informatiky a výpočetní techniky Diplomová práce Inteligentní vyhledávání dokumentů Plzeň 2017 Jiří Martínek Místo této strany bude zadání práce. Prohlášení Prohlašuji, že jsem diplomovou práci vypracoval samostatně a výhradně s použitím citovaných pramenů. V Plzni dne 16. května 2017 Jiří Martínek Poděkování Na tomto místě bych chtěl poděkovat svému vedoucímu diplomové práce doc. Ing. Pavlu Královi Ph.D. za odborné vedení, za pomoc a rady při zpracování této práce. Jiří Martínek Abstract This diploma thesis deals with information retrieval in a set of scanned documents in form of raster images. First, the images are converted into the text form using optical character recognition (OCR) methods. Unfortunately, there are errors in conversion, therefore another part of the work deals with error correction. This thesis propose several error correction methods that are combined to achieve the best possible results. Then, the corrected documents are indexed into the full-text Apache Solr database. The resulting application allows to efficiently find the requested document according to a full-text query. Error correction of the OCR output helps to increase the accuracy of full-text search. The accuracy of the system was experimentally verified on the real data. Abstrakt Tato diplomová práce se zabývá problematikou vyhledávání informací v množině naskenovaných dokumentů v podobě rastrových obrázků. Nejdříve je proto proveden převod rastrového obrázku do textové podoby pomocí metod optického rozpoznávání znaků (OCR). V rámci převodu bohužel dochází k chybám, proto se další část práce zabývá samotnou opravou chyb. V práci je navrženo několik metod oprav chyb, které jsou zkombinovány pro dosažení co nejlepšího výsledku. -

Extracción De Eventos En Prensa Escrita Uruguaya Del Siglo XIX Por Pablo Anzorena Manuel Laguarda Bruno Olivera
UNIVERSIDAD DE LA REPÚBLICA Extracción de eventos en prensa escrita Uruguaya del siglo XIX por Pablo Anzorena Manuel Laguarda Bruno Olivera Tutora: Regina Motz Informe de Proyecto de Grado presentado al Tribunal Evaluador como requisito de graduación de la carrera Ingeniería en Computación en la Facultad de Ingeniería 1 1. Resumen En este proyecto, se plantea el diseño y la implementación de un sistema de extracción de eventos en prensa uruguaya del siglo XIX digitalizados en formato de imagen, generando clusters de eventos agrupados según su similitud semántica. La solución propuesta se divide en 4 módulos: módulo de preprocesamiento compuesto por el OCR y un corrector de texto, módulo de extracción de eventos implementado en Python y utilizando Freeling1, módulo de clustering de eventos implementado en Python utilizando Word Embeddings y por último el módulo de etiquetado de los clusters también utilizando Python. Debido a la cantidad de ruido en los datos que hay en los diarios antiguos, la evaluación de la solución se hizo sobre datos de prensa digital de la actualidad. Se evaluaron diferentes medidas a lo largo del proceso. Para la extracción de eventos se logró conseguir una Precisión y Recall de un 56% y 70% respectivamente. En el caso del módulo de clustering se evaluaron las medidas de Silhouette Coefficient, la Pureza y la Entropía, dando 0.01, 0.57 y 1.41 respectivamente. Finalmente se etiquetaron los clusters utilizando como etiqueta las secciones de los diarios de la actualidad, realizándose una evaluación del etiquetado. 1 http://nlp.lsi.upc.edu/freeling/demo/demo.php 2 Índice general 1. -

Introduction to Digital Humanities Course 3 Anca Dinu
Introduction to Digital Humanities course 3 Anca Dinu DH master program, University of Bucharest, 2019 Primary source for the slides: THE DIGITAL HUMANITIES A Primer for Students and Scholars by Eileen Gardiner and Ronald G. Musto, Cambridge University Press, 2015 DH Tools • Tools classification by: • the object they process (text, image, sound, etc.) • the task they are supposed to perform, output or result. • Projects usually require multiple tools either in parallel or in succession. • To learn how to use them - free tutorials on product websites, on YouTube and other. DH Tools Tools classification by the object they process • Text-based tools: • Text Analysis: • The simplest and most familiar example of text analysis is the document comparison feature in Microsoft Word (taking two different versions of the same document and highlight the differences); • Dedicated text analysis tools create concordances, keyword density/prominence, visualizing patterns, etc. (for instance AntConc) DH Tools • Text Annotation: • On a basic level, digital text annotation is simply adding notes or glosses to a document, for instance, putting comments on a PDF file for personal use. • For complex projects, there are interfaces specifically designed for annotations. • Example: FoLiA-Linguistic-Annotation-Tool https://pypi.org/project/FoLiA-Linguistic-Annotation-Tool/ DH Tools • Text Conversion and Encoding tools: • Every text in digital format is encoded with tags, whether this is apparent to the user or not. • Everything from font size, bold, italics and underline, line and paragraph spacing, justification and superscripts, to meta-data as title and author are the result of such coding tags. • Common encoding standards: XML, HTML, TEI, RTF, etc. -

Abstract: The drivers who drive in other states are unable to recognize the languages on the sign board. So this project helps them to understand the signs in different language and also they will be able to listen it through speaker. This paper describes the working of two module image processing module and voice processing module. This is done majorly using Raspberry Pi using the technology OCR (optical character recognition) technique. This system is constituted by raspberry Pi, camera, speaker, audio playback module. So the system will help in decreasing the accidents causes due to wrong sign recognition. Keywords: Raspberry pi model B+, Tesseract OCR, camera module, recording and playback module,switch. 1. Introduction: In today’s world life is too important and one cannot loose it simply in accidents. The accident rates in today’s world are increasing day by day. The last data says that 78% accidents were because of driver’s fault. There are many faults of drivers and one of them is that they are unable to read the signs and instructions written on boards when they drove into other states. Though the instruction are for them only but they are not able to make it. So keeping this thing in mind we have proposed a system which will help them to understand the sign boards written in regional language.
