It is computed bu the mean value of each cordinate

Xiaolong Zhou

suppose the series of binary mask has been read into a 3D matrix image3D, the following command will calculate the centroid of the object:

regionprops(image3D,'Centroid')

Azhar Imran

Use SOM-RBF Neural Network to calculate the center of the object and then perform any operation accordingly

Jorge Martínez

I think Kalman Filter is your best option.

Alejandro Gonzalez Alzate

Use a simple kalman filter assuming constant velocity for create prediction, then match prediction with current centroids using hungarian algorithm. Finally update the velocity of your model and go to next frame.
