HELIOTEST - Detection of Missing Dots from Printed Patterns

Goals
This project is a sub-project of larger industrial research project Papvision. The goal of this sub-project is to review and revise existing, and develop new methods for an automatic detection of missing dots from printed patterns, such as Heliotest assessment samples. The main goal is to propose new hardware and software solution which meet the industrial requirements for accuracy and reliability.
