Quaternion Affine Moment Invariants for Color Texture Recognition

Abstract

We introduce a generalization of the affine moment invariants for color textures recognition using Quaternion Algebra and present results of experiments on a challenging dataset. The advantage of the proposed method is that it can process color image directly, without losing color information. It is shown that the QAMIs can be obtained from the usual AMIs. Experiments show that color texture descriptors are more efficient and discriminant. Moreover, a new set of invariants can be obtained from each QAMI (due to the non-commutativity of Quaternion algebra).
