Hitachi Similarity Based Image Retrieval System

With the volume of data already at unprecedented levels and expected to continue to increase rampantly, technology enabling quick searches of still and video images is much in demand. In response, Hitachi has developed a Similarity-Based Image Retrieval technology, a search engine for just such large-scale image and video archives. Similarity-Based Image Retrieval technology automatically extracts quantified information intrinsic to the image — such as color, shapes and forms — and runs searches to locate a match. This innovative search technique can be used for something as basic as searching for a movie scene or image on a camcorder to something as complex as searching for facial imagery in security, video surveillance or law enforcement applications.
