1. 1. Improving image quality of a streak camera using periodic shadowing

   Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

   Författare :David-Gabriel Lange; [2021]
   Nyckelord :combustion physics; laser; lock-in amplification; laser induced fluorescence; periodic shadowing; Rhodamine B; streak camera; Mode-locking; microfluidics; fluorescence lifetime imaging; Physics and Astronomy;

   Sammanfattning : Stray light suppression using a method inspired by lock-in amplification, called periodic shadowing, is examined and demonstrated for a measurement involving a streak camera. The experiment consists of resolving the fluorescent decay of the dye Rhodamine B (RhB) and examining both the rise and the decay of the fluorescence. LÄS MER

3. 2. Real-time precipitation suppression in video streams

   Master-uppsats, Lunds universitet/Institutionen för datavetenskap

   Författare :Adam Nilsson; Hoa Truong; [2014]
   Nyckelord :rain-detection; image enhancement; rain-removal; Technology and Engineering;

   Sammanfattning : In surveillance cameras rain and snow can introduce an unwelcome noise to the video stream. The resulting effect of the rain becomes bright streaks in the frames of the video. These streaks can disturb human viewers and image processing algorithms. LÄS MER
