Paper Abstract

Automatic recognition of objects independent of size, orientation, position in the field of view, and color is a difficult and important problem in computer vision, image analysis, and automatic target recognition fields. In this paper we explore the theory of invariant algebra to develop solutions for this problem. Algebraic invariants of binary and ternary quantics are used to obtain features that remain unchanged when the object undergoes linear geometrical and spectral transformations. Empirical examples of the use of this approach on real and synthetic data are provided.
