  1. 1. Padel court detection system

    University essay from Jönköping University/JTH, Avdelningen för datateknik och informatik

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

    Abstract : 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. READ MORE

  3. 2. A heuristic approach to screw pose detection

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

    Author : Emil Ransed; [2022]
    Keywords : ;

    Abstract : 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. READ MORE

  4. 3. Machine-vision-based Detection of Paper Roll Core Eccentricity : Fast and Robust On-Line Measurement Using Circular Hough Transform

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Erik Sehlstedt; [2022]
    Keywords : Eccentricity; Core eccentricity; Paper roll; Machine vision; Computer vision; Hough transform; Circular Hough transform; Defect detection; On-line measurement; Quality control;

    Abstract : The field of computer vision offers tools that allow machines to derive meaningful infor-mation from video and images and consequently make decisions based on visual inputs. In the paper industry, implementation of machine vision (MV) can be used to automate and speed up processes that require visual inspection, particularly certain segments of quality control – one such application being detection and measurement of paper roll core eccentricity.

  5. 4. Characterisation of the epistatic hybrid incompatibility locus STRUBBELIG RECEPTOR FAMILY 3 in Arabidopsis

    University essay from SLU/Department of Plant Biology (from 140101)

    Author : Fredrik Dölfors; [2018]
    Keywords : abiotic stress; arabidopsis; co-evolution; hybrid incompatibility; receptor-like kinase;

    Abstract : Populations of Arabidopsis thaliana have spread throughout temperate zones of the world and adapted to prevailing biotic and abiotic stress factors. Diverging popula-tions of Arabidopsis accessions can evolve postzygotic hybrid incompatibility (HI). READ MORE

  6. 5. Estimation and Correction of the Distortion in Forensic Image due to Rotation of the Photo Camera

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Sathwika Bavikadi; Venkata Bharath Botta; [2018]
    Keywords : Hough Transformation; Hough Circular Transformation; Image Rotation; Forensic Scales.;

    Abstract : Images, in contrast to text, represent an effective and natural communication media for humans, due to their immediacy and the easy way to understand the image content. Shape recognition and pattern recognition are one of the most important tasks in the image processing. READ MORE
