Hausdorff Distances for Searching in Binary Text Images
This work has been partially supported by Grant No. DO 02-275, 16.12.2008, Bulgarian NSF, Ministry of Education and Science. Hausdorff distance (HD) seems the most efficient instrument for measuring how far two compact non-empty subsets of a metric space are from each other. This paper considers the possibilities provided by HD and some of its modifications used recently by many authors for resemblance between binary text images. Summarizing part of the existing word image matching methods,...
A Digital Library of Folklore Songs and Keyword-Based Search Engine
ACM Computing Classification System (1998): H3.3, H.5.5, J5. We present a full text search engine in a digital library of Bulgarian folklore songs - in the lyrics and scores of the songs. The deployment of the digital library on the cloud as well as the technical requirements for providing our data to Europeana are discussed. This work is partially supported by Grant of the Bulgarian National Science Foundation under number DTK-02-54/2009.
Technology for Scanning Astronomical Photographic Plates
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.
Software Tools for Digitization of Astronomical Photographic Plates
ACM Computing Classification System (1998): J.2. In this paper we present tools for helping the process of digitization of astronomical photographic plates. The requirements of Virtual Observatory presume that any FITS file, which contains a digital image, has to be equipped with a complete header. Wide-Field Plate Database (WFPDB) offers most of the meta-data needed for the creation of FITS header. The header2011 software gives the user an appropriate tool for connecting WFPDB catalogues...
Potsdam Library of Astronomical Photographic Plates
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 standards of...
