1. A method of inferring a facial composite comprising: pre-processing a facial image, the pre-processing comprising removing a background light source from the facial image and increasing resolution of the facial image; receiving a user's input regarding a point of the facial image in response to a determination regarding success or failure of the pre-processing; extracting facial feature information regarding an item so as to identify the facial image based on the received user's input; searching a facial type that coincides with the extracted facial feature information using a support vector machine (SVM) from a facial composite database in which feature information according to facial type is learned through the SVM, is classified in a hierarchical structure having a plurality of levels, and is stored; and generating a facial composite for generating a face shape model based on the searched facial type.
