A Novel Approach to Segment Nucleus of Uterine Cervix Pap Smear Cells Using Watershed Segmentation
This paper presents an approach for segmentation of nuclei of uterine cervix pap smear cells using watershed segmentation. The proposed approach consists of manly three steps: preprocessing of pap smear images, formation of improved binary image and application of watershed segmentation to extract nucleus part of pap smear images. The novelty of proposed approach is that it has introduced systematic way to create improved binary image using thresholding and series of morphological operations as explained in proposed methodology Sect. 2. Each single cell image is segmented in three regions namely nucleus, boundary between nucleus and background and background of image.
