1. 6. Club Head Tracking : Visualizing the Golf Swing with Machine Learning

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

   Författare :Fredrik Herbai; [2023]
   Nyckelord :Golf; Machine learning; Neural network; XGBoost; Interpolation; Deep learning; Data collection; Data augmentation;

   Sammanfattning : During the broadcast of a golf tournament, a way to show the audience what a player's swing looks like would be to draw a trace following the movement of the club head. A computer vision model can be trained to identify the position of the club head in an image, but due to the high speed at which professional players swing their clubs coupled with the low frame rate of a typical broadcast camera, the club head is not discernible whatsoever in most frames.

3. 7. Toward Equine Gait Analysis : Semantic Segmentation and 3D Reconstruction

   Master-uppsats, Linköpings universitet/Datorseende

   Författare :Evelina Hult; [2023]
   Nyckelord :Deep Learning; Computer Vision; Semantic Segmentation; Structure-from-Motion; Equine Gait Analysis; Harness Racing Horses; Engineering and Technology; Natural Sciences; Computer Vision Laboratory;

   Sammanfattning : Harness racing horses are exposed to high workload and consequently, they are at risk of joint injuries and lameness. In recent years, the interest in applications to improve animal welfare has increased and there is a demand for objective assessment methods that can enable early and robust diagnosis of injuries.

4. 8. Differences in velocity between the sexes and stages of courtship in a dance fly

   Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Författare :Filip Myllyaho; [2022-02-17]
   Nyckelord :Dansfluga; Hilara maura; höghastighetskamera; partner-val; Dance fly; Hilara maura; high-speed camera; mate choice;

   Sammanfattning : Dance flies (Diptera: Empididae: Empidinae) are famous for their elaborate mating behaviour, which can be broken down to three distinct stages in adults: hunting, swarming, and mating. In many species, males hunt for prey that they present as nuptial gifts to recipient females in swarms, after which the pair will copulate in the air or after landing on nearby vegetation. LÄS MER

5. 9. Framtagning av systemuppställning för dynamisk bildtagning med blixtröntgen : Ett arbete i samarbete med Scandiflash AB

   Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknik

   Författare :Rasmus Lindqvist; David Jerresand; [2022]
   Nyckelord :flash X-ray; high-speed camera; camera lens; dynamic imaging; optics; imaging; optical resolution; scintillator; product development; construction; blixtröntgen; höghastighetskamera; kameraobjektiv; dynamisk bildtagning; optik; avbildning; optisk upplösning; scintillator; produktutveckling; konstruktion;

   Sammanfattning : Inom materialforskning och en stor del av den mekaniska och mekatroniska industrin finns ett intresse av att utnyttja blixtröntgen för att studera dynamiska händelseförlopp i inneslutna system, ej synbara med konventionella kameror. I och med att många rörelser inom de benämna områdena även sker i hyperhastighet så tillåter blixtröntgen statisk bildtagning  av rörelser i flera km/s, med minimal rörelseoskärpa. LÄS MER

7. 10. Gravity and surface tension-driven waves

   Master-uppsats, KTH/Teknisk mekanik

   Författare :Albin Hedblom; [2022]
   Nyckelord :Gravity surface waves; capillary-gravity surface waves; dispersion; experiment;

   Sammanfattning : In this thesis, gravity and surface tension-driven water waves are investigated by designing an experimental setup to track wave patterns using a 300 fps high speed camera. This is done to reproduce the theoretical diagram of the dispersion relation for surface waves in different teaching contexts. Surface waves are dispersive, i.e. LÄS MER
