Video segmentation is a basic step in many video processing applications and automatic video indexing is an important feature in the design of a video database. Wavelet transform has emerged as a powerful tool for analysis and efficient compression of visual information. In this application presentation we review various wavelet based techniques for video segmentation and indexing reported in t...

This research project aimed at producing a high-speed and web-based indexing model solution for high-volumes of metadata database content. Such solution would enable users to index their metadata content within reasonable periods of time. Also, it would enable them to debug and profile the entire indexing process. The produced model involves retrieving high-volume of database metadata content, ...

This paper describes about Audio Indexing, Video Indexing, Content Based Image Indexing, and Content Based Multimedia Indexing i.e. Content-based indexing techniques. Indexing is concerned with compactly storing a large collection of terms and rapidly retrieving a set of candidate terms satisfying some property from a large collection of terms. Index is a structure or object in the database Ind...

With the advent of native and XML enabled database systems, techniques for efficiently storing, indexing and querying large collections of XML documents have become an important research topic. This paper presents the storage, indexing and query processing architecture of eXist, an Open Source native XML database system. eXist is tightly integrated with existing tools and covers most of the nat...

This paper discusses an implementation of database signatures. Previous work demonstrates how to use signatures to reduce base table storage requirements in a data warehouse thereby improving performance of database administration tasks as well as complex queries. This work builds upon prior work by showing how signatures enable efficient indexing. This efficient indexing strategy relies partly...

The multidimensional k-NN (k nearest neighbors) query problem arises in a large variety of database applications, including information retrieval, natural language processing, and data mining. To solve it efficiently, database needs an indexing structure supporting this kind of search. However, exact solution is hardly feasible in multidimensional space. In this paper we describe and analyze an...

Object recognition starts from a set of image measurements (including locations of points, lines, surfaces, color, and shading), which provides access into a database where representations of objects are stored. We describe a complexity theory of indexing, a meta-analysis which identiies the best set of measurements (up to algebraic transformations) such that: (1) the representation of objects ...

The latest Geographic Information System (GIS) technology makes it possible to administer the spatial components of daily “business object,” in the corporate database, and apply suitable geographic analysis efficiently in a desktop-focused application. We can use wireless internet technology for transfer process in spatial data from server to client or vice versa. However, the problem in wirele...
