In this paper we propose a novel approach called three feature functions based on Radon transform directly. The corresponding features are defined as the symmetry of the shape, the width of contour, the fullness of the shape. They reveal the information of visual and the inner structures of shape using characteristics of Radon projective space. Theoretical and experimental results verify that the proposed method has strong capability and robustness in handling a variety of shapes and is invariant to rotation.
