Abstract: According to the singular character of the traditional filter because of its defect in the theory, the morphology method is introduced into digital filtering domain. The fundamental principle of constituting the morphology filter is presented. The defect which confine the effect of morphology method is improved. The effect in the practical application is satisfield.

Key words: Mathematical morphology Digital filtering Structure element Detection of roller profile
