A new series of rotation invariant moments by Lie transformation group theory

Toshio Sakata; Ryuei Nishii; Tan Siang Chin; Ryuichi Sawae

In automatic word recognition, location-scale-rotation invariant features are important. We consider the rotation invariant moments of 2-D imagery. Two new series of invariant moments are derived by Lie theory of the orthogonal transformation group. The infinite series are expressed in terms of regular moments.
