Abstract:

A medical image segmentation method includes: step , initialize of the number of clusters and determine the initial values of the cluster centroids; step , calculate a Hausdorff distance between each cluster centroid and each pixel in the image; step , calculate a membership function of each pixel based on the Hausdorff distance and a Euclid distance between the cluster centroids and each pixel; step , calculate an objective function, cluster the pixels of the image based on the updated membership function, and update the centroid value; and repeating step -, until a difference between two objective function values is less than a threshold value. Then the membership function from the last iteration is a final segmentation.
