Edge Detection In Cytology Using Morphological Filters
Joseph Barba, Yuan Li, J. Gil · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1989
A technique for the semi-automatic detection of cell and nuclear contours in cytological specimens is presented. Gray level images are viewed as stacked binary bit plane images with each bit plane image representing the effect of thresholding the gray level image with multiple gray level windows. A binary morphological edge detector is employed to identify edges on selected bit planes. A simple contour tracking algorithm is used to identify the most likely cell and nuclear contours which are presented to the user for verification.
