Data Extraction from Carte Du Ciel Triple Images

Laskov, Lasko, Tsvetkov, Milcho (2013)

Serdica Journal of Computing

Similarity:

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...

Potsdam Library of Astronomical Photographic Plates

Tsvetkova, Katya, Tsvetkov, Milcho, Kirov, Nikolay, Boehm, Petra, Steinmetz, Matthias, Arlt, Rainer, Enke, Harry, von Berlepsch, Regina (2012)

Serdica Journal of Computing

Similarity:

ACM Computing Classification System (1998): J.2. We present the Potsdam photographic plate library at the Leibniz Institute for Astrophysics Potsdam. It includes plate archives, data from plate index catalogues and extracts from astronomical logbooks, as well as digitized plate images and interfaces for accessing all the available information. The plate index catalogues and the digitized images of the Potsdam astronomical photographic plates are prepared according to the...

The Wide-Field Plate Database: Development and Access via Internet

Tsvetkov, Milcho (2012)

Serdica Journal of Computing

Similarity:

ACM Computing Classification System (1998): J.2. The motivations and results from the first 1.5-year period of the project “Wide-field Plate Database (WFPDB): Development and Access via Internet” (DO-02-273/18.12.2008), approved for funding through a competition held by the Bulgarian National Science Fund in the field of Promotion of Research in Priority Areas, are described. The main direction of the development of the project is digitization and preservation of, and web...

Digital Preservation and Web Access to the Konkoly Observatory Schmidt Telescope Plate Archive

Tsvetkova, Katya, Tsvetkov, Milcho, Holl, András (2012)

Serdica Journal of Computing

Similarity:

ACM Computing Classification System (1998): J.2. The digital preservation of the Konkoly Observatory Schmidt telescope plates, as well as the web access to the plate previews, aim for the preservation of this scientific heritage and the re-use of the astronomical photographic plates in time domain astronomy. The photographic plates used as detectors and information storage at astronomical observations with the Konkoly Schmidt telescope had been obtained in the period 1962–1996. The...

Fusion based analysis of ophthalmologic image data

Jiří Jan, Radim Kolář, Libor Kubečka, Jan Odstrčilík, Jiří Gazárek (2011)

Kybernetika

Similarity:

The paper presents an overview of image analysis activities of the Brno DAR group in the medical application area of retinal imaging. Particularly, illumination correction and SNR enhancement by registered averaging as preprocessing steps are briefly described; further mono- and multimodal registration methods developed for specific types of ophthalmological images, and methods for segmentation of optical disc, retinal vessel tree and autofluorescence areas are presented. Finally, the...

Effective chain complexes for twisted products

Marek Filakovský (2012)

Archivum Mathematicum

Similarity:

In the paper weak sufficient conditions for the reduction of the chain complex of a twisted cartesian product F × τ B to a chain complex of free finitely generated abelian groups are found.

Technology for Scanning Astronomical Photographic Plates

Tsvetkov, Milcho, Tsvetkova, Katya, Kirov, Nikolay (2012)

Serdica Journal of Computing

Similarity:

ACM Computing Classification System (1998): J.2. Here we describe the technology and the experience during the astronomical photographic plate digitization with flatbed EPSON scanners. More than 275000 plates in different observatories in Europe were digitized with such scanners last decade. This work is supported by the BG NSF DO-02-273 and DO-02-275 grants and DFG grant STE: 710/6-1,20.11.2009.
