  1. 1. The Visible and the Invisible : Color Contrast Phenomena in Space

    University dissertation from Stockholm : KTH

    Author : Gertrud Olsson; KTH.; [2009]
    Keywords : HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; color in architecture; color theory; color phenomena; simultaneous contrast; simultané; afterimage; transparency; material and immaterial; color mixture; light-colors; HUMANITIES and RELIGION Aesthetic subjects Art; HUMANIORA och RELIGIONSVETENSKAP Estetiska ämnen Konstvetenskap; TECHNOLOGY Civil engineering and architecture Architecture and architectural conservation and restoration Architecture; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur Arkitektur och bebyggelsevård Arkitektur;

    Abstract : This study deals with the changes in color that arise in space, primarily simultaneous contrast in three dimensions. The typical account of simultaneous contrast is that the contrast phenomenon occurs between two or more color surfaces seen together, thus affecting one another. READ MORE

  2. 2. Texture and color of potato products

    University dissertation from Department of Food Engineering, Lund University

    Author : Sandra Segnini; Lunds universitet.; Lund University.; [2000]
    Keywords : sensory evaluations; potato processing; L*a*b*; French fries; potato chips; Texture; color; Food and drink technology; Livsmedelsteknik; SKOGS- och JORDBRUKSVETENSKAP samt LANDSKAPSPLANERING; FORESTRY; AGRICULTURAL SCIENCES and LANDSCAPE PLANNING;

    Abstract : Texture and color are the most important parameters in the definition of the quality of potato products, but usually their subjective measurements do not give any reproducible results due to the complicating factors related to human perception. In order to understand the factors that can affect the texture and the color of the potato products during processing, instrumental techniques have been developed for quantifying those parameters.

  3. 3. Topics in Content Based Image Retrieval : Fonts and Color Emotions

    University dissertation from Linköping : Linköping University Electronic Press

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

    Abstract : 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.

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

    University dissertation from Institutionen för teknik och naturvetenskap

    Author : Thanh Hai Bui; Linköpings universitet.; Linköpings universitet.; [2005]
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 5. Pattern Recognition Methods for Oral Lesion Classification using Digital Color Images

    University dissertation from Chalmers University of Technology

    Author : Artur Chodorowski; Chalmers tekniska högskola.; Chalmers University of Technology.; [2000]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN; MEDICINE; Elektroteknik; elektronik och fotonik; Electrical engineering; electronics and photonics; supervised classification; pattern recognition; support vector machines; computer-aided diagnosis; color; shape; oral lesions; cancer;

    Abstract : The present thesis addresses the development and application of pattern recognition methods for classification of oral lesions using digital color images as input. The human oral cavity is a site of numerous diseases and two of the common and visually similar lesions are oral leukoplakia and oral lichenoid reactions. READ MORE
