Screening of cervical cytological samples using coherent optical processing. Part 2

This paper is Part 2 of a three-part sequence dealing with coherent optical signal processing methods for screening Pap smears. Part 2 is devoted to model analysis and evaluation. A mathematical cell model is established to develop the radial spatial frequency profiles of representative cells F(rho). The quantity rho(2)|F(rho)|(2) is shown to be most effective in bringing out normal/malignant cell transform differences. Photographic contrast and gamma play a major role in amplifying cell discriminant features and reducing the effects of the aperture contribution.
