Abstract:This paper describes a new non-destructive approach for porosity measurement developed in response to a need for a more accurate porosity measurement method for solid samples. The conventional methods in X-ray CT imaging are based on image segmentation where a threshold is applied at a user-defined value. As a result the uncertainty in the porosity measurement is introduced. Therefore, the new method, called the grey level method, which reflects the phenomenon of image processing and computation of ration betw… Show more
