PICKING - Detection of Paper Surface Defects

Picking example
Processed picking image


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 picking and other surface defects from a printed paper surface, for example, from IGT picking assessment samples. The main goal is to propose new hardware and software solution which meet the industrial requirements for accuracy and reliability.
