  • 3D Scanning of Semitransparent Amber with and without Inclusions
    Publication

    - Year 2021

    This paper is concerned with making 3D scans of semitransparent ambers with and without inclusions. The paper presents results of using a variety of devices applied for this purpose. Equipment used in the experiments includes a 3D laser scanner, a structured light scanner, a stereo camera, a camera array and a tomograph. The main object used in the experiment was an amber with a fossil of a lizard. The paper shows possibilities...

  • Equal Baseline Camera Array—Calibration, Testbed and Applications
    Publication

    - Applied Sciences-Basel - Year 2021

    This paper presents research on 3D scanning by taking advantage of a camera array consisting of up to five adjacent cameras. Such an array makes it possible to make a disparity map with a higher precision than a stereo camera, however it preserves the advantages of a stereo camera such as a possibility to operate in wide range of distances and in highly illuminated areas. In an outdoor environment, the array is a competitive alternative...

  • Automatic evaluation of information credibility in Semantic Web and Knowledge Grid
    Publication

    - Year 2008

    This article presents a novel algorithm for automatic estimation of information credibility. It concerns information collected in Knowledge Grid and Semantic Web. Possibilities to evaluate the credibility of information in such structures are much greater than those available for WWW sites which use natural language. The rating system presented in this paper estimates credibility automatically on the basis of the following metrics:...

  • Exploring contexts of use of cultural objects in virtual museums
    Publication

    - Year 2008

    This paper presents a system which facilitates discovering knowledge about cultural objects. The system is based on semantic modeling of a virtual museum which consists of cultural objects placed in a virtual 3D space. The article describes an extension to the concept of cultural objects which includes information on the use of these objects. This extension enables to place objects in an appropriate context in a virtual museum....

  • Improving depth maps of plants by using a set of five cameras
    Publication

    Obtaining high-quality depth maps and disparity maps with the use of a stereo camera is a challenging task for some kinds of objects. The quality of these maps can be improved by taking advantage of a larger number of cameras. The research on the usage of a set of five cameras to obtain disparity maps is presented. The set consists of a central camera and four side cameras. An algorithm for making disparity maps called multiple...

  • Influence of Aggregating Window Size on Disparity Maps Obtained from Equal Baseline Multiple Camera Set (EBMCS)
    Publication

    - Year 2016

    This paper is concerned with obtaining disparity maps on the basis of images from Equal Baseline Multiple Camera Set (EBMCS). EBMCS consists of a central camera and side cameras. Algorithms for obtaining disparity maps with the use of EBMCS take advantage of aggregating windows similarly to stereo matching algorithms for a stereo camera, a camera matrix or a camera array. The paper analyzes the influence of aggregating window size...

  • Information Retrieval with the Use of Music Clustering by Directions Algorithm
    Publication

    - Year 2013

    This paper introduces the Music Clustering by Directions (MCBD) algorithm. The algorithm is designed to support users of query by humming systems in formulating queries. This kind of systems makes it possible to retrieve songs and tunes on the basis of a melody recorded by the user. The Music Clustering by Directions algorithm is a kind of an interactive query expansion method. On the basis of query, the algorithm provides suggestions...

  • Interactive Query Expansion with the Use of Clustering by Directions Algorithm

    This paper concerns Clustering by Directions algorithm. The algorithm introduces a novel approach to interactive query expansion. It is designed to support users of search engines in forming web search queries. When a user executes a query, the algorithm shows potential directions in which the search can be continued. This paper describes the algorithm and it presents an enhancement which reduces the computational complexity of...

  • Metody rozwiązywania problemu zapisu norm prawnych w postaci ontologii OWL

    Artykuł dotyczy problemu zapisu norm prawnych w postaci umożliwiającej systemom komputerowym automatyczne przetwarzanie treści tych norm i ich interpretowanie. Artykuł przedstawia możliwości wykorzystania komputerów do podawania bieżącego stanu prawnego oraz pełnienia funkcji doradczej. W artykule opisana jest realizacja tego zagadnienia opierająca się na zapisie norm prawnych w postaci ontologii wyrażonych w języku OWL. Zapis...

  • Metody wspomagania wyszukiwania informacji
    Publication

    - Year 2011

    Wyszukiwanie informacji analizowane może być z perspektywy użytkownika i w kontekście tego, jakie czynności może on podjąć, aby odnaleźć interesujące go informacje bez wsparcia ze strony analizatora języka. Użytkownicy stosują wyszukiwarki internetowe, jednak często nie są świadomi pełnego zakresu ich możliwości. Wyszukiwanie za pomocą wyszukiwarek polega na wprowadzaniu zapytań w polu tekstowym. Opracowane zostały liczne metody...

  • Metody wyszukiwania informacji oparte na wyznaczaniu kierunków
    Publication

    - Year 2011

    Rozprawa doktorska poświęcona jest nowej, oryginalnej metodzie klasteryzacji kierunkowej przeznaczonej do wyszukiwania informacji. Metoda ma zastosowanie w przypadku, gdy przeprowadzane jest wyszukiwanie za pomocą zapytań. Mogą to być zarówno zapytania wprowadzane w polu tekstowym wyszukiwarki internetowej, jak i zapytania stosowane podczas wydobywania danych zawartych w sieci semantycznej. Metoda służy do przeprowadzania interaktywnego...

  • Linking music data in executable documents
    Publication

    - Year 2022

    This paper presents the application of Interactive Open Document Architecture (IODA) to music and video data. This architecture was design to create multilayer documents which consist of many files. The paper shows the method of creating media documents on the basis of IODA. These kind of documents were called IODA Media Documents (IMD). IMD have links that connect many different kinds of files containing music and video data....
