Sažetak
The image processing and analysis is interesting non destructive method for determining the number of the residual dirt specks within the defined size classes and the area they occupy in handsheets produced from fibers in different phases of the prints recycling process or produced on the paper. Dirt speck include the ink particles in the deinked pulp. The justification of the image analysis application of handsheet made from the fibers during the different paper recycling phases in dependence to the technique which was used in printing. In results interpretation, the measuring results of the relevant optical factors of the recycled fibers were used and discussed in relation to the division of the size and number of particles obtainer by image analysis. A comparison between the two image analysis software tools is given. Statistical techniques such as factorial design and analysis of variance (ANOVA) were used to interpret the findings.
