2-WAVELENGTH SPATIAL-FILTERING BASED SYSTEM FOR PRESCREENING OF CERVICAL SMEARS

An experimental system for identification of early cervical pathology in mass examination of women is presented. It uses band-pass spatial f requency filtering technique for the fast localization of atypical cel ls by transforming their dark stained nuclei into bright spots whose i ntensities depend on the nuclei diameter. The nuclei of enlarged size, which are the symptom of the disease, are detected by measuring the i ntensity level of the spots. This paper is focused on the problem of a rtifacts rejection by dual wavelength illumination and coherent noise suppression.
