13. The computer-readable medium of claim 12 , wherein the instructions, when executed by the at least one processor, cause the at least one processor to perform the operations of: generating a query feature vector in the objective feature space based on the query face; mapping the query feature vector from the objective feature space into the psychological feature space using the mapping function; accessing a set of search feature vectors in the psychological feature space that are associated with a set of search faces; determining distances between the mapped query feature vector and the search feature vectors; selecting one or more search feature vectors that are within a selected distance of the mapped query vector; and designating images including the search faces associated with the selected search feature vectors as the one or more search result images.
14. The computer-readable medium of claim 13 , wherein the instructions, when executed by the at least one processor, further cause the at least one processor to perform the operation of: mapping the search feature vectors from the objective feature space into the psychological feature space to form the set of search feature vectors in the psychological feature space that are associated with a set of search faces.
