Please define your terms. Please remember that not everyone is familiar with what you are doing. Is this Simulink?

To facilitate fractal image compression we extend the Iterated Function System to allow us to partition an image into pieces which are each transformed separately. A modified affine transformation for Partitioned iterated function have 4 parameters si, oi, ei, fi to mapping between domain blocks and range blocks. my programs already until get range blocks and domain blocks. how to get the parameter affine transform ? systems is

I am sorry but that's not any clearer to me.
