  1. 1. 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. Monocular Golf Ball Tracking and Size Estimation

    University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

    Author : MARKUS PETTERSSON; [2014]
    Keywords : ;

    Abstract : In order to estimate the distance between a moving camera and a golfball, the projective ball size in images is measured. Two methods are evaluated based on their ability to detect golf balls in TV broadcasting images: circular Hough transform and scale-space blob detection. READ MORE
