Query by Image for Efficient Information Retrieval: A Necessity
For the past many years, the authors are using search engine for image retrieval. These search engines use shapes, contents, text and caption based approach for getting relevant image from the web repository. This image repository contains billions of 2D and 3D images as well as relevant information about those images. For shape based approach user has to give dimensions of that particular image for getting relevant response. This paper describes the necessity of an efficient search engine for retrieving information about an image by uploading an image on the search engine or giving image as a query for retrieving information related to that particular image.
