Abstract

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(ρ). The quantity ρ2|F(ρ)|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.
