Abstract: This paper proposes a novel rotation-invariant multi-spectral facial recognition approach (RIMFRA) by using orthogonal polynomials. In the first step, a rotation, illumination and noise invariant local descriptor (RinLd) is proposed to represent the texture patterns… read more here.

Abstract: ABSTRACT We study step skew-products over a finite-state shift (base) space whose fibre maps are injective maps on the unit interval. We show that certain invariant sets have a multi-graph structure and can be written… read more here.

Abstract: We introduce an image based algorithmic tool for analyzing multi-component shapes. The method allocates a number to a shape, herein called a multi-component shape measure. This number/measure is invariant with respect to affine transformations and… read more here.
