Abstract: Given a query image,the content-based image retrieval is a new technique that automatically searches the similar images.Shape is one of the key contents of an image.Combined with the shape recognition and image understanding theory,various shape based image retrieval algorithms can be found in the literature.This paper reviews the latest developed image retrieval approaches from the shape representation point of view.Different from the traditional contour/region rule,the authors firstly classify these algorithms according to the features.Then each method is briefly described and the overall performance is also given according to the MPEG-7 principles.Finally conclusions and the future work are presented.
