Searching for images of people is an essential task for image and video search engines. However, current search engines have limited capabilities for this task since they rely on text associated with images and video, and such text is likely to return many irrelevant results. We propose a method for retrieving relevant faces of one person by learning the visual consistency among results retrieved from textcorrelation-based search engines. The method consists of two steps. In the first step, each candidate face obtained from a text-based search engine is ranked with a score that measures the distribution of visual similarities among the faces. Faces that are possibly very relevant or irrelevant are ranked at the top or bottom of the list, respectively. The second step improves this ranking by treating this problem as a classification problem in which input faces are classified as ’person-X’ or ’non-person-X’; and the faces are re-ranked according to their relevant score infe...
