Ndt-a Comparison Betwen Two Image Analysis Software Tools

Abstract Non-destructive testing method scanner based image analysis is used for dirt speck measurement for the evaluation of prints deinkability in waste paper recycling process. The measurement of dirt specks number and area and size classes distribution in undenked and deinked pulps are presented. Two image analysis software tools Spec*Scan, Apogee System and Proton in measurements are used. As the investigation result, the influence of the printing technique, printing conditions, toner and paper kinds on dirt specks number, area and size classes distribution in both undeinked and deinked pulps has been established. The image analysis results obtained for the software Proton are somewhat greater in regard to those obtained for the software Apogee, but the trend is very similar.
