Abstract:
1. A method for determining similar faces within images based on a user's perception of facial similarity, the method comprising: determining, by one or more processors, inequalities between training faces, where the inequalities represent perceptions of one or more training users regarding a similarity of a first set of two, different training faces relative to a similarity of a second set of two, different training faces; determining, by the one or more processors, training feature vectors in an objective feature space based on the training faces, wherein the training feature vectors are separated by objective differences; optimizing, by the one or more processors, a function over a matrix M that maximizes a correlation between the training feature vectors in the objective feature space and the inequalities; determining, by the one or more processors, a mapping function between the objective feature space and a psychological feature space based on the matrix M; determining, by the one or more processors and based on the determined mapping function, similarity information that indicates human perception of facial similarity; receiving, by the one or more processors, a query image that includes a query face; determining, by the one or more processors, one or more search result images that include at least one face that is similar to the query face based on the similarity information that indicates the human perception of facial similarity; and providing, by the one or more processors, the search result images to a user.
