1. A method of performing image recognition using a plurality of image exemplars, each of the image exemplars having a plurality of features, the method comprising: for each of the image exemplars, determining a first location offset between an actual landmark location for a first landmark in the image exemplar and a predicted landmark location for the first landmark in the image exemplar, the predicted landmark location derived using an image recognition process using a first feature of the image exemplar; deriving a probability that the image recognition process applied using the first feature produces an accurate identification of the first landmark in the image exemplars based on the first location offsets for each of the image exemplars; assigning a weight to the first feature based on the derived probability; and performing the image recognition process on an image, the image recognition process utilizing a voting process, for each of one or more features, for one or more landmarks in the plurality of image exemplars, the voting process for the first feature weighted according to the weight assigned to the first feature.
