Theatre Chapbooks At Scale: A Statistical Comparative Analysis of Typography
Diego Belzarena, Seginus Mowlavi, Paula Casariego Castiñeira +3
The paper introduces a statistical method to automatically compare typefaces in printed historical books, using clustered character prototypes and a significance framework, and dem…
When Low CER is Not Enough: An Analysis of Hallucinations in Vision-Language OCR Systems on Historical Uruguayan Documents
Marina Gardella, Camilo Mari{ñ}o, Diego Belzarena +3
Optical Character Recognition (OCR) is a key component in the digitization of historical archives. Recently, Vision-Language Models (VLMs) have emerged as strong alternatives to tr…
TRAS: An Interactive Software for Tracing Tree Ring Cross Sections
Henry Marichal, Diego Passarella, Gregory Randall
Tree ring marking remains a key step in dendrometry and dendrochronology, but it is often performed manually, making the process time-consuming, subjective, and difficult to scale…
Implementation and discussion of the Pith Estimation on Rough Log End Images using Local Fourier Spectrum Analysis method
Henry Marichal, Diego Passarella, Gregory Randall
In this article, we analyze and propose a Python implementation of the method "Pith Estimation on Rough Log End images using Local Fourier Spectrum Analysis", by Rudolf Schraml and…
UruDendro4: A Benchmark Dataset for Automatic Tree-Ring Detection in Cross-Section Images of Pinus taeda L
Henry Marichal, Joaquin Blanco, Diego Passarella +1
Tree-ring growth represents the annual wood increment for a tree, and quantifying it allows researchers to assess which silvicultural practices are best suited for each species. Ma…
Improving OCR using internal document redundancy
Diego Belzarena, Seginus Mowlavi, Aitor Artola +9
Current OCR systems are based on deep learning models trained on large amounts of data. Although they have shown some ability to generalize to unseen data, especially in detection…
