1. A method of improving the precision of training data used in automated image annotation, categorization, recognition, understanding, or retrieval, comprising the steps of:
providing a digital computer; receiving at the computer a plurality of previously tagged digital images; executing an algorithm on the computer to perform the following operations:
(a) extracting visual and textual features from the tagged images,(b) variably weighting the images based upon the extracted features,(c) computing a reference model for the images based on weighted instances through one or multiple iterations,(d) retaining images with high likelihood of correct tagging based upon the reference model; and using the retained images to train an automated image annotation, categorization, recognition, understanding, or retrieval system. |
