Seal imprint identification based on rotational invariant features
Shexiang Ma · Journal of tianjin University of Technology · 2009
Picking-up rotational invariant features are an important measure on seal imprint identification.In this paper,it mostly discusses invariant features of seal imprint.Invariant features of seal imprint mean the features which are studied are invariant.First,we should pick-up these features,then produce invariant feature vectors,and match vectors.This method is highly accurate.
