Hello,

suppose we have an image function F(x,y) and we apply a transformation T ion
to it, where T is an affine transform, together with a 2d local deformation
D.

So TF= F(sDR(x,y)+(dx,dy))

where s is the scale, R is the rotation and d=(dx,dy) is the translation.

However, in some literature I have seen the above as:

TF=F(s(x,y)+DR(x,y)+(dx,dy))

and my question is which of the two is correct, or are they both the same?

Thank you
V.Z.
