A Survey on Image Retrieval Methods

Abstract

The Image retrieval plays a key role in day-to-days world. This work is a review of various references of various image retrieval methods. This paper starts with discussing the working conditions of text based image retrieval then the content-based retrieval: patterns of use, levels, the role of semantics, and the semantic gap. We briefly discuss about various techniques of content based image retrieval such as retrieval by color, shape and the texture and the various algorithms involved in content based image retrieval. Then the semantic based image retrieval aspects are discussed using local content descriptors the regions are segmented and retrieved the semantic regions of image
