  1. 1. Topics in Content Based Image Retrieval Fonts and Color Emotions

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Martin Solli; Linköpings universitet.; Linköpings universitet.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; image analysis; content based image retrieval; font recognition; color emotions; TECHNOLOGY Information technology Image analysis; TEKNIKVETENSKAP Informationsteknik Bildanalys;

    Sammanfattning : Two novel contributions to Content Based Image Retrieval are presented and discussed. The first is a search engine for font recognition. The intended usage is the search in very large font databases. The input to the search engine is an image of a text line, and the output is the name of the font used when printing the text. LÄS MER

  2. 2. Efficient Image Retrieval with Statistical Color Descriptors

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Linh Viet Tran; Linköpings universitet.; Linköpings universitet.; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; color properties; images; statistical; content-based image retrieval CBIR ; non-parametric density estimators; image database; Kernel; Gram-Schmidt; geometry-based; SOCIAL SCIENCES Statistics; computer and systems science Informatics; computer and systems science Information technology; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap Informatik; data- och systemvetenskap Informationsteknologi;

    Sammanfattning : Color has been widely used in content-based image retrieval (CBIR) applications. In such applications the color properties of an image are usually characterized by the probability distribution of the colors in the image. LÄS MER

  3. 3. Group-Theoretical Structure in Multispectral Color and Image Databases

    Detta är en avhandling från Institutionen för teknik och naturvetenskap

    Författare :Thanh Hai Bui; Linköpings universitet.; Linköpings universitet.; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; group theory; PCA Principal Component Analysis ; CBIR; Content-based Image Retrieval ; filter; color; image; multispectral; database; TECHNOLOGY Information technology Signal processing; TEKNIKVETENSKAP Informationsteknik Signalbehandling;

    Sammanfattning : Many applications lead to signals with nonnegative function values. Understanding the structure of the spaces of nonnegative signals is therefore of interest in many different areas. Hence, constructing effective representation spaces with suitable metrics and natural transformations is an important research topic. LÄS MER

  4. 4. Topics in color measurement

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Lars Mattias Andersson; Linköpings universitet.; Linköpings universitet.; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Color characterizations of printing situations are essential for a correct color reproduction. To obtain a good color characterization, knowledge about the substrate, the printing process and the printer function are all of great importance. LÄS MER

  5. 5. Surface Characterization using Radiometric and Fourier Optical Methods

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Peter Hansson; Uppsala universitet.; [2003]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; Radiometry; Fourier Optics; Surface Characterization; Topography; Reflectance; Color; Paper; Printing; Print quality; Gloss; Light scattering; Shape from shading; Photometric stereo; Optical motion compensation; Filtering; Wiener filter; Lamberts law; Image analysis; Image processing; Machine vision; Teknisk fysik; TECHNOLOGY Engineering physics; TEKNIKVETENSKAP Teknisk fysik;

    Sammanfattning : This thesis treats static and dynamic surface characterization using radiometric and Fourier optical methods. A Fourier optical method has been developed for real time image processing in paper production and printing applications. LÄS MER
