  1. 26. Evaluation of Camera Resolution in Optical Flow Estimation Using Event-Based Cameras

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Simon Hellberg; Dominik Hollidt; [2020]
    Keywords : ;

    Abstract : Developments in event-based camera technology and their recent increase in pixel count raised the question of whether resolution helps the accuracy and performance of algorithms. This thesis studies the impact of resolution on optical flow estimation for event-based cameras. READ MORE

  3. 27. Submesoscale variations in sea surface temperature and salinity - a comparison between satellite data and in situ measurements from a mobile platform

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Kerstin Bergentz; [2020]
    Keywords : Earth and Environmental Sciences;

    Abstract : Sea surface temperature and salinity are important variables for understanding many ocean and climate processes. They can be measured both by in situ sensors and satellite remote sensing, each method with its own advantages and disadvantages. READ MORE

  4. 28. NDVI time series analysis for desert locust outbreak detection and quantification analysis of its impact on vegetation productivity of Sahel

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Evangelos Oikonomopoulos; [2020]
    Keywords : Physical Geography and Ecosystem Analysis; Primary Productivity; Desert Locust; NDVI; Time Series Analysis; Outbreak Detection; Food Security; Sahel; Insect Disturbances; GEM; Earth and Environmental Sciences;

    Abstract : It has been shown that the semi-arid environment of the Sahelian belt plays an important role in the global carbon uptake as the fluctuation of its primary productivity can be determinant for the global carbon uptake. The insect Schistocerca gregaria commonly known as the desert locust is a disturbance factor that can affect the vegetation productivity for consecutive seasons. READ MORE

  5. 29. Principal Component Analysis for STEM-EDS images: Optimal collection parameters

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Isac Lazar; [2020]
    Keywords : Principal Component Analysis; PCA; STEM; data analysis; machine learning; metal machining; materials; materials chemistry; materialkemi; Technology and Engineering;

    Abstract : STEM-EDS is a common technique used for compositional mapping in materials. The vasts amounts of raw data produced by STEM EDS is suitable for advanced analysis using methods in unsupervised machine learning. One powerful method is Principal Component Analysis (PCA) which can automatically discover significant chemical correlations in a sample. READ MORE

  6. 30. A remote-sensing approach to studying drought resistance in Swedish old-growth and production forests

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Julika Wolf; [2020]
    Keywords : Physical Geography and Ecosystem Analysis; drought impacts; old-growth forests; forest management; remote sensing; Earth and Environmental Sciences;

    Abstract : Boreal forest ecosystems are predicted to experience hotter and drier summers due to climate change, leading to more frequently reduced soil water availability and an increased risk of droughts, as was already the case in Northern Europe during the severe summer drought of 2018. Prolonged water stress in forest ecosystems can lead to impacts ranging from reduced photosynthesis to forest dieback. READ MORE
