  1. 16. Insect Event Extraction in LIDAR Images using Image Analysis and Convolutional Neural Networks

    University essay from Lunds universitet/Matematik LTH

    Author : Ludvig Malmros; [2018]
    Keywords : Image analysis; Machine Learning; Mathematics and Statistics;

    Abstract : Insect monitoring has earlier been a manual, tedious and time consuming task that is impossible to do in real time. Thus there exists a need for a real time automatic insect monitoring system for counting and classifying insect for use in scientific research and pesticide spraying control. READ MORE

  3. 17. Feromonbaserad inventering av eklevande långhorningsarter i fem habitattyper i sydöstra Sverige

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Marcus Vestlund; [2017]
    Keywords : Cerambycidae; Pyrrhidium sanguineum; Poecilium alni; Poecilium pusillum; Xylotrechus antilope; GROT; feromonfälla; ek; habitat; artbevarande;

    Abstract : Det intensifierade skogsbruket under de senaste 70 åren tillsammans med det ökade uttaget av avverkningsrester s.k. GROT (grenar och toppar) för biobränsleproduktion har lett till att ett flertal av Sveriges vedlevande insektsarter idag hotas av bristen på död ved. READ MORE

  4. 18. Extracting fungal DNA from drill- and biofilm samples from wood in logs

    University essay from SLU/Dept. of Forest Mycology and Plant Pathology

    Author : Niklas Wickander; [2016]
    Keywords : lichen; DNA-extraction; ITS-region; barcode;

    Abstract : The fungal kingdom is a large group of eukaryotic organisms consisting of more than 100 000 known and an expected number of more than 1 million species with a wide variety of lifestyles. Among these lifestyles is a symbiotic lifestyle that has been of importance for lichen forming fungi. READ MORE

  5. 19. Automating 3D graphics generation using GIS data - Terrain and Road reproduction

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Orvar Segerström; [2015]
    Keywords : ;

    Abstract : In this thesis we evaluate different types of GIS data as well as their use cases in the context of the generation of 3D environments. We explore what kinds of GIS data are suited towards 3D graphics generation, how each type is typically represented and different use cases for each. READ MORE

  6. 20. Building Extraction in 2D Imagery Using Hough Transform

    University essay from Högskolan i Gävle/Avdelningen för Industriell utveckling, IT och Samhällsbyggnad

    Author : Rucong Zou; Hong Sun; [2014]
    Keywords : Straight line extraction; Binarization; Hough transform; Edge feature; Detecting buildings; ;

    Abstract : The purpose of this paper is to find out whether Hough transform if it is helpful to building extraction or not. This paper is written with the intention to come up with a building extraction algorithm that captures building areas in images as accurately as possible and eliminates background interference information, allowing the extracted contour area to be slightly larger than the building area itself.
