  1. 1. Design of a variable focal length optics for a SWIR Earth observation camera

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Sergio David Díaz Martínez; [2021]
    Keywords : ;

    Abstract : This thesis consists of a preliminary design study of a variable focal length optics for a SWIREarth observation camera which is planned to be placed inside a 6U Cubesat. After thesuccess of DRAGO instrument consisting on a SWIR camera onboard a Cubesat, which hasbeen recently launched (January 2021), the Institute of Astrophysics of the Canary Islands(IAC) began this project with the intention of adding zoom optics to SWIR space imagingsystems.

  3. 2. Comparative Study of Vision Camera-based Vibration Analysis with the Laser Vibrometer Method

    University essay from KTH/Industriell produktion

    Author : Pradeep Kumar Muralidharan; Hemanth Yanamadala; [2021]
    Keywords : OpenCV; Motion tracking; motion magnification; vision camera method; FFT; tracker; OpenCV; Rörelsesspårning; Rörelseförstoring; Synkamera -metod; FFT; Spårare;

    Abstract : Vibration analysis is a method that studies patterns in vibration data and measures vibration levels. It is usually performed on time waveforms of the vibration signal directly and on thefrequency spectrum derived by applying the Fourier Transform on the time waveform. READ MORE

  4. 3. Micro-Expression Extraction For Lie Detection Using Eulerian Video (Motion and Color) Magnication

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Gautam Krishna Chavali; Sai Kumar N V Bhavaraju; Tushal Adusumilli; VenuGopal Puripanda; [2014]
    Keywords : Micro Expressions; Emotions; Eulerian Video Magnification; Histogram of Oriented Gradients; Voila-Jones Algorithm; Artificial Neural Networks; Support Vector Machines; Pattern Recognition and Classification; Master of Science Programme in Electrical Engineering with emphasis on Signal Processing Masterprogram i Elektroteknik med inriktning mot signalbehandling;

    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

  5. 4. 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

  6. 5. Hur rör sig huden på en häst? : validering av metodik för rörelseanalys av halskotpelaren hos häst

    University essay from SLU/Dept. of Anatomy, Physiology and Biochemistry

    Author : Eva Olsson; [2013]
    Keywords : hudförskjutning; halskotpelare; häst; rörelseforskning; hudmarkörer; skin displacement; equine; motion analysis; skin markers;

    Abstract : Höghastighetsfilmning är en teknik som ofta används inom rörelseforskning på häst, särskilt för att registrera ledrörelse. Reflektoriska hudmarkörer sätts på anatomiska landmärken, vilka sedan filmas med höghastighetskameror. En felkälla med dessa mätningar är att huden förskjuts jämfört med underliggande skelett.
