Full textThe massive digitization of heritage documents raised new prospects for Research like the restoration of the degraded documents. These degradations are due to the bad conditions of conservation and even to the digitization process. Images of old and degraded documents cannot be the retored directely by classical approaches. Hence, we propose in this thesis to develop and analyze document image restoration algorithms. We are mainly interested in foreground/background degradations, since they harm the legibility of the digitized documents and limit the processing of these images. For background degradations, considered as a problem of the superposition of layers, we propose two-based segmentation methods. The first is a recursive approach that relies on the k-means clustering algorithm and the principal component analysis. The second method is an improvement of the initial algorithm of MeanShift in an attempt to reduce its complexity. For foreground degradations, we propose to tackle the problem with PDE-based diffusion approaches. This solution has many useful features that are relevant for use in character restoration. Our comparative study of existing methods allows us to select the best approaches well adapted to our problem. We propose also a new diffusion method preserving singularities and edges while smoothing. Our previously proposed solutions, the diffusion and the Mean-Shift algorithms, are used with success in a joint iterative framework to solve foreground and background degradations. This framework generates segmented images with more reduced artefacts on the edges and on the background than those obtained in separate application of each method

Full textIn the last two decades, the increase in document image digitization projects results in scientific effervescence for conceiving document image processing and analysis algorithms (handwritten recognition, structure document analysis, spotting and indexing / retrieval graphical elements, etc.). A number of successful algorithms are based on learning (supervised, semi-supervised or unsupervised). In order to train such algorithms and to compare their performances, the scientific community on document image analysis needs many publicly available annotated document image databases. Their contents must be exhaustive enough to be representative of the possible variations in the documents to process / analyze. To create real document image databases, one needs an automatic or a manual annotation process. The performance of an automatic annotation process is proportional to the quality and completeness of these databases, and therefore annotation remains largely manual. Regarding the manual process, it is complicated, subjective, and tedious. To overcome such difficulties, several crowd-sourcing initiatives have been proposed, and some of them being modelled as a game to be more attractive. Such processes reduce significantly the price andsubjectivity of annotation, but difficulties still exist. For example, transcription and textline alignment have to be carried out manually. Since the 1990s, alternative document image generation approaches have been proposed including in generating semi-synthetic document images mimicking real ones. Semi-synthetic document image generation allows creating rapidly and cheaply benchmarking databases for evaluating the performances and trainingdocument processing and analysis algorithms. In the context of the project DIGIDOC (Document Image diGitisation with Interactive DescriptiOn Capability) funded by ANR (Agence Nationale de la Recherche), we focus on semi-synthetic document image generation adapted to ancient documents. First, we investigate new degradation models or adapt existing degradation models to ancient documents such as bleed-through model, distortion model, character degradation model, etc. Second, we apply such degradation models to generate semi-synthetic document image databases for performance evaluation (e.g the competition ICDAR2013, GREC2013) or for performance improvement (by re-training a handwritten recognition system, a segmentation system, and a binarisation system). This research work raises many collaboration opportunities with other researchers to share our experimental results with our scientific community. This collaborative work also helps us to validate our degradation models and to prove the efficiency of semi-synthetic document images for performance evaluation and re-training

Full textThe goal of this thesis is to add some tools in order to upgrade image quality when scanning with book digitization.First Chapter talks about image scanner whitout lighting control. This problem focuses to document camera. The goal is to correct lighting. We will see some corrections and we will suggest our method. For this part, we detect pixel's background document and we will rebuild the background of the image by them. With this information, we can correct lighting.Second chapter presents some way to do quality control after digitization, specially out of focus problem. We will enumerate different point of view to analyse and to estimate this information. To validate descriptors, we suggest to blur any picture and to compute blur estimation in order to evaluate precision. After that, we propose to combinate descriptors by machine learning.Third chapter mentions color management problem. Every image devices need to be calibrated. This chapter will expose how to calibrate scanner and explain it. We will see that L*a*b* color space is the connection profil space. To calibrate color, we must transform scanner color space to L*a*b*. We will see, in order to convert information, solution depends color chart used but we show a link between the function and thenumber of patch

Full textOver the last few years, there has been tremendous growth in digitizing collections of cultural heritage documents. Thus, many challenges and open issues have been raised, such as information retrieval in digital libraries or analyzing page content of historical books. Recently, an important need has emerged which consists in designing a computer-aided characterization and categorization tool, able to index or group historical digitized book pages according to several criteria, mainly the layout structure and/or typographic/graphical characteristics of the historical document image content. Thus, the work conducted in this thesis presents an automatic approach for characterization and categorization of historical book pages. The proposed approach is applicable to a large variety of ancient books. In addition, it does not assume a priori knowledge regarding document image layout and content. It is based on the use of texture and graph algorithms to provide a rich and holistic description of the layout and content of the analyzed book pages to characterize and categorize historical book pages. The categorization is based on the characterization of the digitized page content by texture, shape, geometric and topological descriptors. This characterization is represented by a structural signature. More precisely, the signature-based characterization approach consists of two main stages. The first stage is extracting homogeneous regions. Then, the second one is proposing a graph-based page signature which is based on the extracted homogeneous regions, reflecting its layout and content. Afterwards, by comparing the different obtained graph-based signatures using a graph-matching paradigm, the similarities of digitized historical book page layout and/or content can be deduced. Subsequently, book pages with similar layout and/or content can be categorized and grouped, and a table of contents/summary of the analyzed digitized historical book can be provided automatically. As a consequence, numerous signature-based applications (e.g. information retrieval in digital libraries according to several criteria, page categorization) can be implemented for managing effectively a corpus or collections of books. To illustrate the effectiveness of the proposed page signature, a detailed experimental evaluation has been conducted in this work for assessing two possible categorization applications, unsupervised page classification and page stream segmentation. In addition, the different steps of the proposed approach have been evaluated on a large variety of historical document images
