    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

  3. 2. 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
