2D spectral methods for technical documents investigation

Industrial image processing and spectroscopy competences were further developed in the project “2D spectral methods for technical documents investigation”. Various spectroscopic methods were applied and analysis algorithms were optimized to provide a tool for forensic tasks. In the studied case it was necessary to identify the correct sequence of signatures placed on documents.

The method is also useful for numerous other applications such as the detection of undesired contaminations in food products.
