IEEE International conference on multimedia and Expo (ICME)

作者： Shih-Wei Sun Chun-Shien Lu Pao-Chi Chang Department Electrical Engineering National Central University Chungli Taiwan Institute of Information Science Academic Sinica Taipei Taiwan Department Communication Engineering National Central University Chungli Taiwan

In this paper, a new multimedia joint fingerprinting and encryption (JFE) scheme embedded into the advanced access content system (AACS) is proposed. Like other security-related systems, there exist some security threats to the proposed framework. To cope with these difficulties, the contributions of this paper include: (i) we apply multimedia encryption at different points to resist some attacks points; and (ii) we propose rewritable fingerprint embedding (RFE) to deal with some multi-point collusion attacks. Experimental results are provided to demonstrate the proposed AACS-compatible JFE method.

Multi-phase interval caching for a news on demand server

Multi-phase interval caching for a news on demand server

引用

IEEE International conference on multimedia Computing and systems (ICMCS)

作者： Yong Woon Park Won ii Seo Ki Dong Chung Department of Computer Science Pusan National University Busan South Korea

We propose a buffer cache algorithm to build a cost effective storage server for real time news objects. In a news on demand server the number of concurrent streams is bounded for the maximum disk bandwidth the NOD server provides. The maximum numbers of concurrent streams can be increased more than the total disk bandwidth supports if the buffer cache is applied to hold hot news objects. However it is said that conventional caching algorithms do not go well with real time news objects. With our proposed caching scheme all of the news objects are classified based on their arrival rate; their eligibility is then checked for caching. Only suitable objects are permitted to access the buffer pool to reduce unnecessary buffer replacement. We use simulation to verify the efficiency of our proposed algorithm and our results show that by using this caching scheme, compared with servicing requested streams only by disks, a greater number of requests are serviced without extra cost.

International conference on Distributed Computing systems

作者： R. Luling Department of Mathematics and Computer Science University of Paderborn Germany

This paper presents principles and algorithms for the management of a network of media servers. Such a server network allows the online delivery of broadband multimedia data, e.g. audio and video streams, to a large number of widely distributed clients. Thus, the implementation of large scale distributed broadband media information services is possible if such networks can be handled efficiently. In the paper two new combinatorial optimization problems are defined that have to be solved for an efficient management of the distributed media servers connected by a high-bandwidth communication network. The algorithms consider the case of a static mapping of media assets onto the server network as well as the dynamic migration of media assets on such a network. The first scenario is used in the case that all media assets are loaded for the first time onto the server network. The second scenario is applied dynamically during run-time of an information service taking the varying user access pattern and changing media content of the server network into account. In this paper the algorithms are presented and their efficiency is demonstrated using some benchmark instances. The algorithms are part of a larger distributed system that allows the management of a network of distributed media servers. The principles of this system are presented as well as some applications that have been developed and are supported by this distributed server management system (DSMS).

IEEE International conference on multimedia and Expo (ICME)

Providing natural and efficient access to the fast growing multimedia information, accommodating a variety of user skills and preferences, is a critical aspect of content-based information mining. Query by humming provides a natural means for content-based retrieval from music databases. A statistical pattern recognition approach for recognizing hummed or sung melodies is reported in this paper. Being data-driven, the proposed system aims at providing a robust front-end especially for dealing with variability in user's productions. The segment of a note in the humming waveform is modeled by a hidden Markov model (HMM) while data features such as pitch measures are modeled by Gaussian mixture models (GMM). Preliminary real-time recognition experiments are carried out based on humming data obtained from eight users and an overall correct recognition rate of around 80% is demonstrated.

Adaptive filtering for delivering multimedia services in W-CDMA cellular networks using genetic algorithms

International conference on Wireless Networks, Communications and Mobile Computing

作者： F. De Angelis I. Habib City College City University of New York USA

This paper presents an adaptive filtering algorithm for the delivery of multimedia content with different quality of service (QoS) requirements in time-varying wideband code-division multiple access (W-CDMA) cellular networks. The algorithm objective is to guarantee levels of quality for two different user defined profiles (premium, or economy), while attempting to maximize the allocation of the radio channel bandwidth and maintaining the QoS requirements of downloaded traffic flows (audio, video, and data). Our proposed solution is based upon utilizing genetic algorithms (GAs) to solve a multi-objective function that selects, during a control period, the bit rates and formats for the media codecs of downloaded traffic flows and assigns the air interface channel rate and power to each user, subject to different constraints. To show the performance of the algorithm, W-CDMA systems with and without filtering capabilities are compared.

作者： Arthur T. Gómez Luan C. Nesi Marcio G. Martins Leonardo D. Chiwiacowsky Master Program on Applied Computing University of the Sinos Valley São Leopoldo/RS Brazil

The advent of the digital television in Brazil has allowed users to access interactive channels. Once interactive channels are available, the users are able to find multimedia content such as movies and breaking news programs, to send and/or receive emails, to access interactive applications and also other contents. In this context, a high demand of requests from users is expected. Therefore, from the content provider's point of view, the determination of transmission parameters is needed in order to ensure the best quality of transmission to every user. The aforementioned identification problem is modelled as an optimization problem and a solution procedure based on metaheuristic techniques is proposed. Genetic Algorithm and Tabu Search metaheuristics are employed separately and coupled in a hybrid scheme to define the best transmission policy, optimizing the transmission parameters, such as audio and video transmission rates. Based on the experimental results, the hybrid algorithm has produced better solutions which meet the quality requirements.

Time split linear quadtree for indexing image databases

Time split linear quadtree for indexing image databases

引用

IEEE International conference on Image Processing

作者： T. Tzouramanis M. Vassilakopoulos Y. Manolopoulos Lab of Data Engineering Department of Informatics Aristotle University of Thessaloniki Thessaloniki Greece

The time split B-tree (TSBT) is modified for indexing a database of evolving binary images. This is accomplished by embedding ideas from linear region quadtrees that make the TSBT able to support spatio-temporal query processing. To improve query performance, additional pointers are added to the leaf-nodes of the TSBT. The resulting access method is called time split linear quadtree (TSLQ). algorithms for processing five spatio-temporal queries have been adapted to the new structure. Such queries appear in multimedia systems, or geographical information systems (GIS), when searched by content. The TSLQ was implemented and results of extensive experiments on query time performance are presented, indicating that the proposed algorithmic approaches outbalance respective straightforward algorithms. The region data sets used in the experiments were real images of meteorological satellite views and synthetic raster images.

Real-time content-based processing of multicast video

Real-time content-based processing of multicast video

Asilomar conference on Signals, systems & Computers

The access of high bandwidth multimedia data is generally limited to the network due to the limited network resources, inefficient indexing mechanism and less of semantic interpretations. Currently, most content-based video content representation involves the segmentation and indexing of video based on scene change and camera/object motion, and such research generally performs off-line video processing. Little research has been done on on-line video processing, which is crucial in video communication applications such as video conferencing, video multicasting and on-line video browsing and retrieval. This research investigates real-time content-based processing of multicast video over the Internet. New on-line video feature extraction schemes, such as scene change detection, on-line key frame classification, are considered to meet the requirement of real-time video multicasting filtering based on the user's profile over the Internet. The annotation and features extracted from a multicast videoconference bitstream by the on-line video content analysis proxies, which are using the proposed video processing algorithms, are output to a separate metadata channel for the further assistance of semantic multicasting of video content. The performance of the proposed algorithms is also demonstrated.

Present day mobile phones have evolved as multimedia devices, where users can capture and store photos, videos on their mobile phones. As the amount of digital multimedia content expands, it becomes increasingly difficult to find specific images in the device, giving rise to problems of organization, storing and retrieval of images. To improve human access to a large unstructured data in their personal collections on mobile phones, there is a need for effective and precise retrieval algorithms for the user to search browse and interact with these collections in real time. Retrieval algorithms are highly complex and this characteristic becomes more intense on mobile platform due to restrictions in architecture and computing power. In this paper we propose a speech based image retrieval algorithm for personal collections optimized for porting on to a mobile phones. We have treated the speech spectrogram as an image and applied trace transformation to obtain an unique and robust identifier string that acts as a fingerprint for image retrieval systems. Trace transform is popular in image processing algorithms because it is robust to affine transforms for feature extraction. The proposed algorithm exhibits optimization in memory and retrieval time costs.
