Here the data corresponds to the centroid locations of multiple objects on a sequence of images. There are 51 images and roughly 15 objects in each frame. Now , I want to extract the centroid of each of the objects from different frames and put them in separate arrays. , wherein each array is identified by its object number. I am not able to write the right code for this, could some one ps give me some idea, or a rough sketch of the code snippet.

You might do this with a cell array.
