  1. 1. Padel court detection system

    Kandidat-uppsats, Jönköping University/JTH, Avdelningen för datateknik och informatik

    Författare :David Wennerblom; Andrey Arronet; [2023]
    Nyckelord :Court detection; Computer vision; Image processing; Padel; Hough lines; Canny edge detector; Homography; OpenCV;

    Sammanfattning : The aim of this thesis is to examine the possibility of a court detection program for sports videos that can identify the court even when some important elements are not visible. The study will also analyze what external factors may impact the program's accuracy in detecting all relevant elements. LÄS MER

  3. 2. A heuristic approach to screw pose detection

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Emil Ransed; [2022]
    Nyckelord :;

    Sammanfattning : Object detection using vision systems could generally be accomplished using machine learning or conventional computer vision techniques. This thesis implements and compares three methods to locate screws on a flat plane using conventional computer vision on regular non stereo images without any depth or range information. LÄS MER

  4. 3. Detecting and comparing Kanban boards using Computer Vision

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Humam Behnam; [2022]
    Nyckelord :Kanban Board; Sticky Notes; Computer Vison; OpenCV; Feature Detection; Feature Matching; Canny Edges; Contours; Perspective Transformation; Text Detection; Kanbantavla; Klisterlappar; Datorseende; OpenCV; Funktionsdetektering; Funktionsmatchning; Cannykanter; Konturer; Perspektivförvandling; Textigenkänning;

    Sammanfattning : This thesis investigates the problem of detecting and tracking sticky notes on Kanban boards using classical computer vision techniques. Currently, there exists some alternatives for digitizing sticky notes, but none keep track of notes that have already been digitized, allowing for duplicate notes to be created when scanning multiple images of the same Kanban board.

  5. 4. Lokalisering av brunnar i ELISpot

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Ylva Modahl; Caroline Skoglund; [2019]
    Nyckelord :Biomedical imaging; Image analysis; Image edge detection; Digital signal processing; Hough transform; Canny Operator.;

    Sammanfattning : Health is a fundamental human right. To increase global health, research in the medical sector is of great importance. Decreasing time consumption of biomedical testing could accelerate the research and development of new drugs and vaccines. This could be achieved by automation of biomedical analysis, using computerized methods. LÄS MER

  7. 5. DEVELOPMENT OF A LOW-COST VISION SYSTEM FOR FINDING CONTOUR AND SURFACE DEFECTS ON CAST IRON ENGINE COMPONENTS

    Master-uppsats, KTH/Industriell produktion

    Författare :Alex Kiviorg; [2014]
    Nyckelord :;

    Sammanfattning : The thesis aims to develop an image processing algorithm for a 2D vision system for quality inspection of cast iron components (size 250x190x120mm). The system is designed to be low cost and be an easily implementable solution for an existing production line to complement or replace part of manual quality inspection. LÄS MER
