Content-based Image Retrieval Mei Wu Faculty of Computer Science Dalhousie University
Motivation • The huge amount of images, resulting from the fast development of multimedia and the wide spread of internet, makes user-labelled annotation method “mission impossible”. • People are seeking for automatic image retrieval methods which are based on images own contents, such as color, texture and shape, rather than manually-labelled annotations. • CBIR can be broadly used in areas, such as crime prevention, medical diagnosis, satellite imaging and online searching.
