Hierarchical graph-based media content representation for real time search in large scale multimedia databases
نویسندگان
چکیده
This paper presents a system architecture and the appropriate algorithms for confidential searching of multimedia digital libraries. The proposed scheme uses Middleware service layer that allows pre-processing of raw content with technology owned by the Search Engine, without compromising the security of the original architecture in any way. The specific search algorithms described are a hierarchical graph structure algorithm for preprocessing, and a backtracking search algorithm that achieves good real-time performance (speed, and precision-recall values) under the given security constraints.

Dynamic Segmentation Of Videos Based on Spatio-Temporal Pyramid Matching In Large Scale Video Retrieval System
Tremendous growth in the field of multimedia technology has headed to large and detailed multimedia databases. Broadcasting of digital video content on different media brings the search of copies in large video databases to a new critical issue. Content Based Copy Detection (CBCD) presents an alternative to the watermarking approach to identify video sequences and to solve this challenge.Multim...
متن کاملA partition-based algorithm for clustering large-scale software systems
Clustering techniques are used to extract the structure of software for understanding, maintaining, and refactoring. In the literature, most of the proposed approaches for software clustering are divided into hierarchical algorithms and search-based techniques. In the former, clustering is a process of merging (splitting) similar (non-similar) clusters. These techniques suffered from the drawba...
متن کاملA universal k-tree model for content-based multimedia retrieval
In this paper, we propose a unified model for indexing and retrieving multimedia data using characteristic features and multiresolution processing. Each multimedia datatype, such as audio and video, is represented as a k-dimensional signal in the spatio-temporal domain. A k-dimensional signal is transformed into characteristic features (contents) and these features are stored in a hierarchical ...
متن کاملMultimedia Indexing, Search, and Retrieval in Large Databases of Social Networks
Social networks are changing the way multimedia content is shared on the web, by allowing users to upload their photos, videos, and audio content, produced by any means of digital recorders such as mobile/smart-phones, and web/digital cameras. This plethora of content created the need for finding the desired media in the social media universe. Moreover, the diversity of the available content, i...
