Press felt is a product that is being used in paperindustry. In order to evaluate the production process whenpress felts are made, it is necessary to be able to estimate thefiber sizes in product. Here we are estimating the depthdistribution of different sizes of fibers in a press felt sample.We developed a program in Matlab to process X-ray imagesof a press felt, scanned by micro-CT scanner that is able to findthe fibers of two different known sizes of fibers and estimates the depth distribution of the different fibers.
