An Approach to E cient Storage , Retrieval , and Browsing of LargeScale Image

چکیده
This paper suggests a wavelet transform based multiresolution approach as a viable solution to the problems of storage, retrieval and browsing in a large image database. We also investigate the performance of an optimal uniform mean square quantizer in representing all transform coeecients to ensure that the disk space necessary for storing a multiresolution representation does not exceed that of the original image. In addition, popular wavelet lters are compared with respect to their reconstruction performance and computational complexity. We conclude that, for our application, the Haar wavelet lters ooer an appropriate compromise between reconstruction performance and computational eeorts.

متن کاملAn Intelligent Multimedia System for E cient Image Browsing and Retrieval
In this work, an integrated system is proposed for e cient image browsing and retrieval in multimedia databases. The system incorporates intelligent management and content-based retrieval schemes on top of a fundamental multimedia database structure. Agents are employed in order to limit search into minor subsets of the database. This concept is applied in all modules of the proposed system, mi...

Content-based image retrieval and text-based image retrieval are two fundamental approaches in the field of image retrieval. The challenges related to each of these approaches, guide the researchers to use combining approaches and semi-automatic retrieval using the user interaction in the retrieval cycle. Hence, in this paper, an image retrieval system is introduced that provided two kind of qu...
متن کاملAccurate Image Retrieval Based on Compact Composite Descriptors and Relevance Feedback Information
In this paper a new set of descriptors appropriate for image indexing and retrieval is proposed. The proposed descriptors address the tremendously increased need for e±cient content-based image retrieval (CBIR) in many application areas such as the Internet, biomedicine, commerce and education. These applications commonly store image information in large image databases where the image informat...
متن کاملAdaptive storage and retrieval of large compressed images
Enabling the e cient storage, access and retrieval of large volumes of multi-dimensional data is one of the important emerging problems in databases. We present a framework for adaptively storing, accessing, and retrieving large images. The framework uses a space and frequency graph to generate and select image view elements for storing in the database. By adapting to user access patterns, the ...
