1. Design of a variable focal length optics for a SWIR Earth observation camera
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : 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.

2. Comparative Study of Vision Camera-based Vibration Analysis with the Laser Vibrometer Method
Master-uppsats, KTH/Industriell produktionSammanfattning : 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. LÄS MER
3. Micro-Expression Extraction For Lie Detection Using Eulerian Video (Motion and Color) Magnication
Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandlingSammanfattning : 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. LÄS MER
4. VIDEO COLOUR VARIATION DETECTION AND MOTION MAGNIFICATION TO OBSERVE SUBTLE CHANGES
Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapSammanfattning : 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. LÄS MER
5. Hur rör sig huden på en häst? : validering av metodik för rörelseanalys av halskotpelaren hos häst
Master-uppsats, SLU/Dept. of Anatomy, Physiology and BiochemistrySammanfattning : 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. LÄS MER
