Abstract
An imaging system comprising: a pair of cameras (2, 3) adapted to capture images in the near infrared region of the electromagnetic spectrum; a camera (4) adapted to capture images in the visible region of the electromagnetic spectrum; a near-infrared light source (5); and a controller (6). The system configured to obtain a plurality images of the face of an individual and, from a local binary pattern distribution of image pixels, determine the age of the individual in each of the images by applying a linear regression technique and computing an average.

A method of estimating an individual's age comprising the steps of:
- obtaining a plurality of images of the individual;
- locating the face of the individual in each of the plurality of images of the individual;
- locating facial landmarks of the face of the individual in each of the plurality of images of the individual;
- mapping the face of the individual in each of the plurality of images of the individual onto a previously determined face shape template such that the position of facial landmarks in each image coincides with corresponding facial landmarks in the previously determined face shape template;
- cropping each of the plurality of images of the individual to form a plurality of face region images;
- comparing each pixel in each face region image with a plurality of nearest neighbour pixels to determine a plurality of image pixel values;
- creating a plurality of image distributions from the plurality of image pixel values;
- determining a plurality of age estimation values by applying a linear regression process to each of said plurality of image distributions;
- and
- determining the individual's age by averaging said plurality of age estimation values.
An imaging apparatus comprising:
- a pair of cameras adapted to capture images in the near infrared region of the electromagnetic spectrum;
- a camera adapted to capture images in the visible region of the electromagnetic spectrum;
- a near-infrared light source;
- and
- a controller.
