correction for constant drift of the center of mass

[Denis ROUEDE]

dear Sir , Mme

I am working with  a stack of images.

Each image of the stack shows different objects at different locations.

Ideally, even if the objects are different in each image, the center of mass of these objects is the same for each image of the stack.

I have noticed a constant drift of the center of mass and I would like to correct all images from this drift in order to have the center of mass perfecly aligned for all images of the stack.


Turboreg reg does not work because the objects are different for each image of the stack.  

thank you if someone can help
