<p>A user interface automatically retrieves the preference of a user when a user interacts with a system by detecting his/her image and matching the user image database. The image database stores the physical features of users of a system, which can differentiate between the users of the system. A user registration method transparently registers user into the image database through clustering using learned distance metric from user images. A method of learning a distance metric identifies pair-wise constraints from data points and maximizes the margin between the distances of a first set of pairs and a second set of pairs, which can be further solved via semi-positive definite programming.</p> |
