Abstract: Age progression of a test facial image is facilitated by compiling training data, including a training set(s) having selected initial images of subjects by gender and age-group. In addition, the age progression includes manipulating the training data, including: for a given age-group of a training set, substantially aligning respective face shapes; determining a common frame based on the aligned shapes; substantially aligning respective face appearances to generate a shape-free form corresponding to the face appearance of each subject, using the substantially aligned shapes to generate an age-specific shape-dictionary for each age-group, and a common shape-dictionary for the age-groups of the training set, and using the aligned appearances to generate at least an age-specific appearance-dictionary for each age-group, and a common appearance-dictionary for the age-groups of the training set.

Abstract: A mechanism is provided for two-directional biometric matching. The mechanism receives a first biometric record and a second biometric record for matching. The mechanism performs a first matching process using a matching algorithm of the first record to the second record to obtain a first matching outcome. The mechanism performs a second matching process using the same matching algorithm of the first matching process, wherein the second record is matched to the first record to obtain a second matching outcome. The mechanism compares the first and second matching outcomes to determine if there is a difference in outcome.
