Gabor Weber Local Descriptor for Bovine Iris Recognition

Abstract EN

Iris recognition is a robust biometric technology.

This paper proposes a novel local descriptor for bovine iris recognition, named Gabor Weber local descriptor (GWLD).

We first compute the Gabor magnitude maps for the input bovine iris image, and then calculate the differential excitation and orientation for each pixel over each Gabor magnitude map.

After that, we use these differential excitations and orientations to construct the GWLD histogram representation.

Finally, histogram intersection is adopted to measure the similarity between different GWLD histograms.

The experimental results on the SEU bovine iris database verify the representation power of our proposed local descriptor.
