【Abstract】 This thesis mainly discusses the content-based image retrieval system and technology. It presents the model and feature of content-based image retrieval system,and then discusses some methods of feature abstraction and similarity measurement based on color, texture and shape. The improved experiment result of retrieval based on image and texture is given finally.更多还原
