Abstract

Aspects of the disclosure provide an iris recognition system. The iris recognition system can include a three-dimensional (3D) sensor that is configured to capture a 3D image of an iris, an iris feature extractor that is configured to generate an iris template based on the 3D image of the iris, and a memory that is configured to store the iris template.

Claims (23)

1. An iris and face recognition system, comprising:

a three-dimensional (3D) sensor that is configured to capture a 3D image of an iris and a face including depth information and different perspective views of the iris and the face;

an iris feature extractor that is configured to generate an iris image quality score and an iris template based on the 3D image of the iris and the face;

an iris comparator that is configured to compare the iris template against an iris template stored in an iris database to generate an iris match score;

a face feature extractor that is configured to generate a face image quality score and a face template based on the 3D image of the iris and the face;

a face comparator that is configured to compare the face template against a face template stored in a face database to generate a face match score; and

a fuser that is configured to fuse the iris match score and the face match score to generate a fusion score.

2. The iris and face recognition system of claim 1 , further comprising:

an illuminator that is configured to provide illumination in a visible or infrared light spectral band for the 3D sensor to capture the 3D image of the face and the iris.

3. The iris and face recognition system of claim 1 , wherein the fuser is configured to use the iris image quality score and the face image quality score to fuse the iris match score and the face match score to generate a quality-based fusion score.

4. The iris and face recognition system of claim 1 , wherein the 3D sensor is a microlens array light field camera (LFC).

5. A method for three-dimensional (3D) iris and face recognition, comprising:

capturing a 3D image of an iris and a face with a three-dimensional (3D) sensor, the 3D image including depth information and different perspective views of the iris and the face;

generating an iris image quality score and an iris template based on the 3D image of the iris and the face;

comparing the iris template against an iris template stored in an iris database to generate an iris match score;

generating a face image quality score and a face template based on the 3D image of the iris and the face;

comparing the face template against a face template stored in a face database to generate a face match score; and

fusing by a fuser the iris match score and the face match score to generate a fusion score.

6. The method of claim 5 , further comprising:

providing illumination in a visible light spectral band for the 3D sensor to capture the 3D image of the face and the iris.

7. The method of claim 5 , wherein fusing the iris match score and the face match score includes:

using the iris image quality score and the face image quality score to fuse the iris match score and the face match score to generate a quality-based fusion score.

8. The method of claim 5 , wherein the 3D sensor is a microlens array light field camera (LFC).
