Abstract: During the past decades we have been observing a permanent increase in image data, leading to
huge repositories. Content-based image retrieval (CBIR) methods have tried to improve the access
to image data. To date, numerous feature extraction methods have been proposed to improve the
quality of CBIR and image classification systems. In this paper, we are analyzing the technique of
relevance feedback for the purpose of image retrieval system. The survey is used to study all the
methods used for image retrieval system. The structure-based features its task as broad as texture
image retrieval and/or classification. To develop a structure based feature extraction, we have to
investigate CBIR and classification problems. |
