Segmentation of Brain Tissues from MRI Images Using Multitask Fuzzy Clustering Algorithm

Algorithm 1

WMT-FCM.

	Initialization: set the number of tasks T, the number of private centers, the number D of public centers, the termination threshold ε, fuzzy index m, the maximum number K of iterations, and the parameters and .
	Results: the final partition matrix and cluster centers for each task.
	for t = 1,…, T do
	Randomly initialize cluster centroids and weights for the tth task;
	end
	Randomly initialize public clustering centroids;
	for k = 1,…, K do
	Update for each task using equation (11)
	Update for each task using equation (14)
	Update using equation (12)
	Update using equation (15)
	Update using equation (17)
	Calculate the fitness using equation (5)
