In this paper, a new affine invariant is presented. Using this invariant, we apply a robust algorithm to find the correspondence between two different affine transformed point sets. Application of this method to form registration is presented. Assuming that a blank sample of the form is available, a new algorithm is derived for registering a filled-in form to its blank counterpart for extraction of the filled in data
