Abstract:
1. Face recognition apparatus, comprising: a face recogniser trainable using image data defining a plurality of images of a face of a subject person to generate a trained face recogniser storing representation data characterising the face and operable to process image data defining an image using the representation data to determine if the image contains the subject person's face; a data store to store data identifying at least one age of the subject person characterised by the representation data as date data for the representation data; an age difference calculator operable to calculate an age difference for the subject person in dependence upon the stored date data for the representation data; a confidence measure calculator operable to calculate a confidence measure in dependence upon both the calculated age difference for the subject person and an age of the subject person characterised by the representation data, the calculated age difference being indicative of the reliability of the result of face recognition processing by the trained face recogniser using the representation data; and an output generator operable to generate an output in dependence upon the calculated confidence measure for alerting a user if the confidence measure indicates that the reliability of the result of face recognition processing may not be sufficiently high.
