TECHNOLOGY Image Retrieval by Content Using Descriptors
P. A. Hemalatha · 2013
Image retrieval from large databases has become ea sier nowadays through the digitization of images. O ne such methodology which is widely used forms the image retrieval by its content. CBIR enhances the tech nique of retrieving images from a larger collection. QBIC ha s achieved its necessity by retrieving the appropri ate images by using its features to retrieve the images. Features can be of one of the following- Shape, Color and T exture. This paper makes use of descriptors to retrieve the text ure and the color features. Texture feature is extr acted by making use of Edge histogram and color feature is extracte d by using HMMD color space. The feature extraction phase is applicable for both query image and database images. These features are processed and stored as anothe r database named feature database which is later used to match the query image with the feature database images. Similarity measure is calculated between the images through a distance measure and hence similar images are retri eved that matches the specific criteria.
