Abstract

Unlike real or complex numbers, quaternion multiplication does not satisfy the commutative law. This makes it impossible to generalize some conclusions on semi-tensor product to quaternion directly, which is valid on real or complex number fields. In this paper, we define semi-tensor product of quaternion matrices and study the properties of semi-tensor product of quaternion matrices, and the conclusion is applied to the color digital image restoration model.
