  1. 1. Video Processing for Nail-fold Capillary Blood Velocity Detection

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Chen Wang; [2015]
    Keywords : Video analysis; nail-fold capillary; blood velocity detection;

    Abstract : Microcirculation plays an essential and functional role in the human body and reflects people’s physical status with microscopic detail. For peripheral microcirculation, nail-fold microscopy is a convenient and non-invasive tool since the capillaries in the nail-fold are well arranged and parallel to the skin, which is advantageous for microscopic visualization.

    Abstract : Lie-detection has been an evergreen and evolving subject. Polygraph techniques have been the most popular and successful technique till date. The main drawback of the polygraph is that good results cannot be attained without maintaining a physical contact, of the subject under test. READ MORE

  4. 3. VIDEO COLOUR VARIATION DETECTION AND MOTION MAGNIFICATION TO OBSERVE SUBTLE CHANGES

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Hussnain Javaid; Taimour Khan Babar; Ayyaz Rasool; Raja Umer Saghir; [2013]
    Keywords : Gaussian Pyramid; Laplacian Pyramid; Motion Magnification; Steerable Pyramid; Video Magnification.;

    Abstract : Our thesis work is based on revealing minor informative variations in a video which are hard to perceive, that can be further exaggerated to extract hidden variations of color and motions in a video. In our thesis we apply di erent techniques of a video decomposition like Laplacian, Steerable and Gaussian pyramids to observe the improvement in performance of the videos. READ MORE
