  1. 1. Machine Vision Based Quality Control and Fault Detection in a Textile Dyeing Machine

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Evelina Morgan; Valter Möller; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Fault detection systems come in a variety of formats and are used in many different types of machines and industries. They can be used to perform fast and accurate detection, classification and analysis. The need for user interaction can be decreased and by that the general level of automation can be increased.

  3. 2. Finding license-plates in varying lighting conditions using two machine learning methods

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Författare :André Sturesson; Johannes Böök; [2023]
    Nyckelord :machine learning; license plate; image recognition;

    Sammanfattning : Object detection and machine learning are important fields in Computer science. This report presents two methods to find the bounding box of a license plate and tries to evaluate the best approach to deal with various lighting conditions. LÄS MER

  4. 3. The influence of neural network-based image enhancements on object detection

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för informationsteknologi

    Författare :Eric Pettersson; Muhammed Al Khayyat; [2023]
    Nyckelord :Object detection; YOLO; image enhancement; ESRGAN; Zero-DCE;

    Sammanfattning : This thesis investigates the impact of image enhancement techniques on object detection for carsin real-world traffic scenarios. The study focuses on upscaling and light correction treatments andtheir effects on detecting cars in challenging conditions. Initially, a YOLOv8x model is trained on clear static car images. LÄS MER

  5. 4. Comparison of Autofocus Methods for Highly Reflective Surfaces : A Case Study on the Inspection of Optical Filters

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Axel Hedvall; [2023]
    Nyckelord :autofocus; reflective surface; optical filter; visual inspection; autofokus; reflekterande yta; optiskt filter; visuell inspektion;

    Sammanfattning : Visual inspection is a crucial final step when manufacturing products, as it determines if a product can be sold or rejected. The inspection is often performed manually by trained inspectors, which is time-consuming and often subjective. By automating the inspection, it can be performed faster and more accurately. LÄS MER

  7. 5. Procedural Natural Texture Generation on a Global Scale

    Master-uppsats, Linköpings universitet/Informationskodning

    Författare :Anna Pohl Lundgren; [2023]
    Nyckelord :computer graphics; procedural generation; procedural textures; gpu; image processing; satellite imagery; real time; real-time; shadow detection;

    Sammanfattning : This Master’s thesis investigates the application of dynamically generated procedural terrain textures for texturing 3D representations of the Earth’s surface. The study explores techniques to overcome limitations of the currently most common method – projecting satellite imagery onto the mesh – such as insufficient resolution for close-up views and challenges in accommodating external lighting models.
