Claim One:
1. A method for facial image bucketing, comprising: analyzing each of a plurality of facial images in a candidate image set, comprising: determining, for the each image, a location of each of a plurality of face points; computing, for the each image, a distance between the location of each of the plurality of face points; and computing, for the each image, a ratio for each unique pair of the computed distances; selecting, from the computed ratios for the plurality of facial images, at least one particular one of the computed face ratios; clustering the facial images in the candidate image set into a plurality of buckets using the selected at least one particular one of the computed face ratios, comprising iteratively computing a mean and a standard deviation, according to the at least one particular one of the computed face ratios, for each of at least one image to be included in each of the plurality of buckets until achieving convergence; and performing a query for a query facial image by comparing the query facial image only to images clustered into a selected subset of the plurality of buckets.
