  1. 1. Automation of forest road inventory using computer vision and machine learning

    University essay from Umeå universitet/Institutionen för fysik

    Author : Jacques de Flon; [2023]
    Keywords : Computer vision; Machine Learning; Image recognition; forestry; road inventory; pothole; gravel road;

    Abstract : There are around 300, 000 kilometer of gravel roads throughout the Swedish countryside, used every day by common people and companies. These roads face constant wear due to harsh weather as well as from heavy traffic, and thus, regular maintenance is required to keep up the road standard. READ MORE

  3. 2. Identification of shape errors in a parabolic solar collector : An improvement to the analysing algorithms examining the solar collector from optical measurements

    University essay from Umeå universitet/Institutionen för fysik

    Author : Malin Gelfgren; [2023]
    Keywords : ;

    Abstract : Increasing global warming with droughts, forest fires and melting polar ice has forced the world to speed up the transition from fossil fuel to fossil free energy. A big part of it is the use of solar energy. To obtain solar thermal energy, different sorts of solar collectors have been developed. READ MORE

  4. 3. A Machine Learning Approach for Comprehending Cosmic Expansion

    University essay from KTH/Fysik

    Author : Ludvig Doeser; [2021]
    Keywords : Cosmology; Cosmic expansion; Galaxy Images; Machine learning; Kosmologi; kosmisk expansion; galaxbilder; maskininlärning;

    Abstract : This thesis aims at using novel machine learning techniques to test the dynamics of the Universe via the cosmological redshift-distance test. Currently, one of the most outstanding questions in cosmology is the physical cause of the accelerating cosmic expansion observed with supernovae. READ MORE

  5. 4. Indoor triangulation system using vision sensors

    University essay from Uppsala universitet/Signaler och system

    Author : Torun Nicander; [2020]
    Keywords : positioning; triangulation; vision sensor; computer vision;

    Abstract : This thesis aims to investigate a triangulation system for indoor positioning in two dimensions (2D). The system was implemented using three Pixy2 vision sensors placed on a straight baseline. A Pixy2 consists of a camera lens and an image sensor (Aptina MT9M114) as well as a microcontroller (NXP LPC4330), and other components. READ MORE

  6. 5. Depth of Field Rendering from Sparsely Sampled Pinhole Images

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

    Author : Natalie Axelsson; [2020]
    Keywords : ;

    Abstract : Optical lenses cause foreground and background objects to appear blurred, causing an effect called depth of field. Each point in the scene is projected onto the imaging plane as a semitransparent circle of confusion (CoC) with diameter depending on the distance between the point and the lens. READ MORE
