The method

Keeping in mind the above characteristics of the problem, we propose a mathematical method which has as data only the pictorical contents.

• Develop the images supported on circles with a special basis of eigenfunctions of each rotation operator

• Compare the coefficients of this development to deduce the matching between the images, with the care to control the aliasing errors with the projection of the images on a special finite subspace invariant by rotation and respected by the sampling operation
