A Latin Private Document on Papyrus (ChLA XLIV 1300 recto)

Highly Degraded Recto-verso Document Image Processing and Understanding

can be interpreted as matching of an input graph (keyword) with a large set of graphs (document). More formally, in order to spot a certain keyword wi, all p graph instances gi1, ... , gip of that word wi occurring in the training set are matched against all graph words in each text line using our adapted graph matching procedure. That is, for a given word wi and a specific text line s pairwise...

A Document Recognition System for Early Modern Latin

Large-scale digitization of manuscripts is facilitated by high-accuracy optical character recognition (OCR) engines. The focus of our work is on using these tools to digitize Latin texts. Many of the texts in the language, especially the early modern, make heavy use of special characters like ligatures and accented abbreviations. Current OCRs are inadequate for our purpose: their built-in train...

Séparation recto/verso d’un document par modélisation markovienne à double couche

Nous proposons un modèle markovien à deux couches pour la séparation des deux faces d’un document, dont une seule face a été numérisé. A l’aide de deux champs de Markov séparés, un pour chaque face, chaque pixel est modélisé par deux variables cachées connectées par une unique variable observée. L’avantage de cette formulation est une meilleure adaptation au processus ayant créé l’image observé...

Public-Private Partnerships in Latin America: A Review Based on Four Case Studies

Npgrj_NN_1543 1298..1300

In this study, we assess the impact of normal aging on top-down modulation, a cognitive control mechanism that supports both attention and memory by the suppression and enhancement of sensory processing in accordance with task goals. Using fMRI (functional magnetic resonance imaging), we show that healthy older adults demonstrated a prominent deficit in the suppression of cortical activity asso...
