|
SummaryThe Columbia TAG (Transductive Annotation by Graph) system is deigned to facilitate rapid retrieval and exploration of large image and video collections. It incorporates novel graph-based label propagation methods and intuitive graphic user interfaces (GUI) that allow users quickly browse and annotate a small number of images/videos, and then in real or near real time receive refined labels for all remaining unlabeled data in the collection. Using such refined labels, additional positive images/videos matching user's interest can be quickly discovered. It can be used as a fast search system alone, or a bootstrapping system for developing additional target recognition tools needed in critical image application domains such as intelligence, surveillance, consumer, biomedical, and Web. The diagram of TAG system is shown below.
