Content-Based Indexing of Multimedia Databases
Content-based retrieval of multimedia database calls for content-based indexing techniques. Different from conventional databases, where data items are represented by a set of attributes of elementary data types, multimedia objects in multimedia databases are represented by a collection of features; similarity of object contents depends on context and frame of reference; and features of objects...
متن کاملAn Efficient Indexing and Search Technique for Multimedia Databases
We present a novel index-based approach for searching multimedia databases by content. Our approach integrates methods from classical full-text retrieval with the mathematical concept of groups acting on sets. This yields a flexible framework applicable to a wide range of content-based search problems such as audioor image-identification. We propose space-efficient indexing methods as well as v...
متن کاملWavelet-based Indexing of Audio Data in Audio/Multimedia Databases
The phenomenal increase in the amounts of audio (and multimedia) data being generated, processed, and used in several computer applications have necessitated the development of audio (and multimedia) database systems with newer features such as content-based queries and similarity searches to manage and use such data. Example applications of audio databases are in digital libraries, entertainme...
متن کاملTransform-Based Indexing of Audio Data for Multimedia Databases
Since the relative proportion of multimedia (video, image and audio) data within databases is expected to increase substantially in the future, keyword-based indexing would be inadequate and eecient content-based query and retrieval are required. The problem of devising content-based query, indexing, and retrieval for these newer data types remains an open and challenging problem. While conside...
متن کاملVector Approximation based Indexing for High-Dimensional Multimedia Databases
the proliferation of multimedia data, there is an increasing need to support the indexing and searching of high-dimensional data. In this paper, we propose an efficient indexing method for high-dimensional multimedia databases using the filtering approach, known also as vector approximation approach which supports the nearest neighbor search efficiently. Our technique called RA +-Blocks (Region...
