In static imaging analysis the image microscopic image of the particle is binarized into background and particle by one or two thresholds. It is necessary that the particles shows a difference in contrast to the background. In the binarized image the 2 dimensional representation of the particle is measured by algorithms and the particles size and shape information is determined. Depending on the filters
material different algorithms are chosen for the binarization and illumination. At rap.ID we use the Single Particle Explorer for this analysis on all kinds of samples such as Polyester filter disks, Cellulose Nitrate and gold coated polycarbonate core pore membrane filters such as the patented filtr.AID. Partilce overlapping single fields are stitched together to single fibers.
