  1. 11. Photoplethysmographic heart and respiratory rate monitoring : instrument design and evaluation

    Författare :Håkan Ugnell; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : A new optical heart and respiratory rate monitor utilising the photoplethysmographic (PPG) signal is presented.The PPG method, first developed in the 1930s, is based on the fact that incident light to the skin surface is absorbed, scattered and reflected in tissue and blood.

  3. 12. Applied problems and computational methods in radiative transfer

    Författare :Magnus Neuman; Per Edström; Daniel Åberg; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Light scattering in turbid media is essential for such diverse applications as paperand print, computer rendering, optical tomography, astrophysics and remote sensing.This thesis investigates angular variations of light reflected from plane-parallelturbid media using both mathematical models and reflectance measurements, dealswith several applications and proposes novel computational methods for solving thegoverning equations.

  4. 13. Efficient Image Retrieval with Statistical Color Descriptors

    Författare :Linh Viet Tran; Reiner Lenz; Björn Kruse; Linköpings universitet; []
    Nyckelord :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;

    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

  5. 14. Ink-paper interaction : a study in ink-jet color reproduction

    Författare :Li Yang; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : An ink jet printing system consists of three fundamental parts: inks, printing engine, and substrates. Inks are materials creating color by selectively absorbing and scattering the visible illumination light. The printer acts as an ink distributor that governs the ink application. LÄS MER
