Title Cytological Low-Quality Image Segmentation
Abstract Since 1950, conventional cytology uses glass slides for microscopic analysis of cervical cells, in order to perform Pap Test. Such method yields low-quality images and overlapping cells, which both hampers their analysis and classification. Several countries use a modern method for the realization of Pap test called ThinPrep because it offers high-quality images and overcome the problem of overlapping cells. Our goal is to present a technique for segmenting digital images obtained from conventional cytology method on glass slides. The technique uses Watershed Transform and K-Means Clustering in order to find cell markers or seeds. Nonlinear regression is applied as a way to refine the markers and to allow the Watershed Transform utilization.
