Hi guys,

I have a simple question, but cannot find the optimal solution.

I have two binary images, with a random X and Y shift, and without rotation. I want to register the images in order to find out what is the X/Y shift.

I can manually move 1 image around the other to find the best match. but I think there is something much easier out there.

please help.

Try normxcorr2() in the Image Processing Toolbox.

thanks for the reply. the function description says "The matrix A must be larger than the matrix template for the normalization to be meaningful. The values of template cannot all be the same"

is this the right method? could you please elaborate a little more.

many thanks
