Dividing into equal areas over time with object drift

Hi everybody

I need some help and I found this post. I would like to create a circular area divided into equal areas, so the macro developed by @oburri is almost perfect for me. But I have a stack of images of the same plane over time, so I need to create the same area throughout the entire video. the problem is that my cell of interest, moves slightly over the video time. I have the coordinates of the center of mass of the cell for each time. I was wondering if it is possible to create an area within each slice, in which the center of mass, coincides with the center of mass of the cell.

any help you can give me is very useful

Thanks a lot
