Image Projective Invariants
Erbo Li, Hanlin Mo, Dong Xu +1
In this paper, we propose relative projective differential invariants (RPDIs) which are invariant to general projective transformations. By using RPDIs and the structural frame of…
Reflection Invariant and Symmetry Detection
Erbo Li, Hua Li
Symmetry detection and discrimination are of fundamental meaning in science, technology, and engineering. This paper introduces reflection invariants and defines the directional mo…
Isomorphism between Differential and Moment Invariants under Affine Transform
Erbo Li, Hua Li
The invariant is one of central topics in science, technology and engineering. The differential invariant is essential in understanding or describing some important phenomena or pr…
Shape DNA: Basic Generating Functions for Geometric Moment Invariants
Erbo Li, Yazhou Huang, Dong Xu +1
Geometric moment invariants (GMIs) have been widely used as basic tool in shape analysis and information retrieval. Their structure and characteristics determine efficiency and eff…
