Comparative Study on Automated Cell Nuclei Segmentation Methods for Cytology Pleural Effusion Images

Algorithm 8

: K-means clustering method.

(1)	Select k cluster centers
(2)	For each pixel of an image, find its closest center and assign to the closest class
(3)	Update every center as the mean of its points
(4)	Repeat until it convergence or when there are no changes during the assignment step, or when the average distortion per point decreases slightly
(5)	Reshape the cluster pixels into the image.
