  2. 6. Image Based Visualization Methods for Meteorological Data

    Author : Björn Olsson; Anders Ynnerman; Reiner Lenz; Anders Hast; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Visualization; Meteorological Data; Artificial Neural Networks; High-Dynamic-Range images; Satellite Data; Classification; Computer science; Datavetenskap;

    Abstract : Visualization is the process of constructing methods, which are able to synthesize interesting and informative images from data sets, to simplify the process of interpreting the data. In this thesis a new approach to construct meteorological visualization methods using neural network technology is described. READ MORE

  4. 7. Color Emotions in Large Scale Content Based Image Indexing

    Author : Martin Solli; Reiner Lenz; Björn Kruse; Stephen Westland; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Traditional content based image indexing aims at developing algorithms that can analyze and index images based on their visual content. A typical approach is to measure image attributes, like colors or textures, and save the result in image descriptors, which then can be used in recognition and retrieval applications. READ MORE

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

    Author : Martin Solli; Reiner Lenz; Jan Erik Solem; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; image analysis; content based image retrieval; font recognition; color emotions; Image analysis; 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.

  6. 9. Incident Light Fields

    Author : Jonas Unger; Anders Ynnerman; Reiner Lenz; Alan Chalmers; Linköpings universitet; []
    Keywords : Computer Graphics; Image Based Lighting; Photorealistic Rendering; Light Fields; High Dynamic Range Imaging; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Image based lighting, (IBL), is a computer graphics technique for creating photorealistic renderings of synthetic objects such that they can be placed into real world scenes. IBL has been widely recognized and is today used in commercial production pipelines. However, the current techniques only use illumination captured at a single point in space. READ MORE

  7. 10. Efficient Image Retrieval with Statistical Color Descriptors

    Author : Linh Viet Tran; Reiner Lenz; Björn Kruse; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; color properties; images; statistical; content-based image retrieval CBIR ; non-parametric density estimators; image database; Kernel; Gram-Schmidt; geometry-based; Information technology; Informationsteknologi;

    Abstract : 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. READ MORE
