Claim:
1. A method for facial image bucketing, comprising: analyzing each of a plurality of facial images in a candidate image set, comprising: selecting, for the candidate image set, a subset of the facial features; clustering the facial images in the candidate image set into a plurality of buckets according to the image-specific ratio for each facial feature in the selected subset, comprising iteratively computing a mean and a standard deviation, according to the image-specific ratio for each facial feature in the selected subset, for each of at least one image to be included in each of the plurality of buckets until achieving convergence; and storing the plurality of buckets on a storage medium for subsequent use in performing a query for a query facial image to determine which of the plurality of facial images is most similar to the query facial image, wherein the query facial image is compared only to images clustered into a selected subset of the plurality of buckets.
