Paper Abstract

Fully automated screening of cervical smears by high resolution digital image processing systems has been aimed at for more than ten years. Despite the use of sophisticated systems and a special preparation up to now no system has proved its ability to replace the cytotechnologist. The main problems are the high information content of the samples and the limited speed of sequential digital processors. As a solution to the speed problem analogue optical processing methods have been proposed. We have built an inexpensive and compact opto-electronic system that is adapted to the way a highly trained cytotechnologist screens a sample. It uses spatial frequency plane filtering for fast information reduction. Due to their limited accuracy and low flexibility sample classification by exclusive use of optical processors is not possible. Therefore our system is intended only as an interactive screening aid to facilitate human cytoscreening and leaves the classification of the slide to the cytotechnologist. In principle it can also be used to speed up digital image processing systems.
