In this paper an approach to document line segmentation is presented. The algorithm is based on a wavelet transform of the horizontal
projective profile of the document image. The projective profile is examined as a one-dimensional discrete signal which is decomposed using the pyramidal wavelet algorithm up to a precise scale, where local minima and maxima are discovered. These local extrema, projected into the input signal, correspond...

Recently, the digitalization of the astronomical scientific heritage has been considered an important task that can facilitate much researches in astronomy. The creation of digital libraries and databases of astronomical photographic plates brings up the problem of digitalization astronomical logbooks, since the data contained in them is crucial for the usage of the plates. An optical character recognition (OCR) system for the handwritten...
This article presents the principal results of the doctoral thesis “Recognition of neume
notation in historical documents” by Lasko Laskov (Institute of Mathematics and Informatics at
Bulgarian Academy of Sciences), successfully defended before the Specialized Academic Council
for Informatics and Mathematical Modelling on 07 June 2010.
Byzantine neume notation is a specific form of note script, used
by the Orthodox Christian Church since ancient times until nowadays for
writing music...
Carte du Ciel (from French, map of the sky) is a part of a 19th
century extensive international astronomical project whose goal was to map
the entire visible sky. The results of this vast effort were collected in the
form of astrographic plates and their paper representatives that are called
astrographic maps and are widely distributed among many observatories and
astronomical institutes over the world. Our goal is to design methods and
algorithms to automatically extract data from digitized Carte...
