the problem of automatic signature recognition has received little attention incomparison with the problem of signature verification, despite its potentialapplications for many business processes and can be used effectively in paperlessoffice projects. this paper presents model-based off-line signature recognition withrotation invariant features. non-linear rotation of signature patterns is one...

this article concerned on the study of signature submanifolds for curves under lie group actions se(2), sa(2) and for surfaces under se(3). signature submanifold is a regular submanifold which its coordinate components are dierential invariants of an associated manifold under lie group action, and therefore signature submanifold is a key for solving equivalence problems.

Despite the severe criticism expressed by some of the reviewers, after studying their comments and the suggested references, we still believe that our results are original, correct, and potentially important for the systems and control community. Detailed answers to the reviewers’ comments with rebuttal and explanation of the corrections/additions in the revised version of the paper are given i...
