Research ArticleOpen accessIn the abstractRobust Image Watermarking Using Discrete Wavelet TransformDhandapani Samiappan, Krishnan AmmasiProblem statement: Digital Watermarking have gained popularity in recent years as a means of protecting multimedia data from illegal copying and unlawful reproduction. It is mainly used for copyright protection of multimedia data. Approach: In this study an image watermarking algorithm which is blind (do not require the presence of host image for detection) and robust is proposed. Results: The … …Journal of Computer Science, Vol. 7, Issue 1 · 16 Dec 2010 · 8,142 accessesView PDFCite
Research ArticleOpen accessIn the abstractSuccessive Image Interpolation Using Lifting Scheme ApproachRohini S. Asamwar, Kishor Bhurchandi, A. S. GandhiProblem statement: Fast and accurate interpolation and resizing of images and video frames is a much sought after research area in multimedia applications. The more accurate schemes are computationally expensive and require more time for execution. We proposed here Discrete Wavelet Transform (DWT) using lifting scheme as an accurate and computationally inexpensive interpolation technique for image resizing. Approach: In this … …Journal of Computer Science, Vol. 6, Issue 9 · 30 Sep 2010 · 7,573 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Multi-form Multiple Choice Editor Exam Tool Based on HTML Website and Artificial Intelligence TechniquesA. Rjoub, Y. Eyadat, A. Ghazawi et al.Problem statement: The educators argue that in the post modern world changes in the nature of work, globalization, the information revaluation and today's social challenges will all impact on educational priorities and thus will require a new mode of assessment. Approach: The objectives of this study were to: (1) Present a novel software package tool to create multiple choice and … …Journal of Computer Science, Vol. 5, Issue 6 · 30 Jun 2009 · 7,033 accessesView PDFCite
Research ArticleOpen accessIn the abstractImage Compression and Reconstruction using Cubic Spline Interpolation TechniqueR. Muthaiah, K. NeelaKantan, Vidur Sharma, Amit AroraA new dimension of image compression using random pixels of irregular sampling and image reconstruction using cubic-spline interpolation techniques proposed in this paper. It also covers the wide field of multimedia communication concerned with multimedia messaging (MMS) and image transfer through mobile phones and tried to find a mechanism to transfer images with minimum bandwidth requirement. This method would provide … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 7,197 accessesView PDFCite
Research ArticleOpen accessIn the abstractConfigurable Multirate Filter BanksAli Al-HajMultimedia communications require efficient and real-time implementations of multirate digital signal processing systems. The backbone structures of multirate systems are digital multirate filter banks. Therefore, efficient multimedia communications rely, in the first place, on real-time implementations of multirate filter banks. In this paper, we describe a Field Programmable Gate Array (FPGA) implementation of the analysis and synthesis filter banks which … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 6,379 accessesView PDFCite
Research ArticleOpen accessIn the abstractCombined DWT-DCT Digital Image WatermarkingAli Al-HajThe proliferation of digitized media due to the rapid growth of networked multimedia systems, has created an urgent need for copyright enforcement technologies that can protect copyright ownership of multimedia objects. Digital image watermarking is one such technology that has been developed to protect digital images from illegal manipulations. In particular, digital image watermarking algorithms which are based on the … …Journal of Computer Science, Vol. 3, Issue 9 · 30 Sep 2007 · 18,200 accessesView PDFCite
Research ArticleOpen accessIn the abstractOntology-based Knowledge Networks for users' training: The Enterprise Resource Planning (ERP) caseMacris AristomenisThis paper presents a prototype model for the design and development of training material, where both the multimedia objects used in training scenarios and the knowledge built into them are captured and fully reusable. Knowledge found in the logic, the structure and the ways of use of domain specific literacy is represented as a knowledge network (a collection of educational … …Journal of Computer Science, Vol. 2, Issue 9 · 30 Sep 2006 · 6,659 accessesView PDFCite
Research ArticleOpen accessIn the abstractCulture and Managerial Styles: A Study of Potential Managers in MalaysiaStanley Richardson, Yeap Peik FoongMultimedia University, (MMU) is the oldest and largest private university in Malaysia (a multiracial country). Its main campus in Cyberjaya, Selangor has four Faculties: Creative Multimedia (FCM), Information Technology (FIT), Engineering (FOE) and Management (FOM). English is the language of instruction.

Research ArticleOpen accessIn the abstractAnalysis of the Prospects for Developing Storage and Processing Complexes for Multiformat Media DataVladimir Zhanovich Kuklin, Islam Alexandrovich Alexandrov, Alexander Alexandrovich Umyskov, Abas Khasanovich LampezhevA distinctive feature of multifunctional systems for supporting multimedia services on a single platform is the heterogeneity of incoming streams and requests, which requires optimization of resource use under physical constraints. In this regard, it is relevant to develop promising proposals for the functional structure and technical characteristics of complexes for storing and processing multi-format media data, which was the … …Journal of Computer Science, Vol. 18, Issue 12 · 6 Dec 2022 · 5,577 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Comparative Analysis of Various Approaches for Incorporating Contextual Information into Recommender SystemsQuang-Hung Le, Son-Lam Vu, Anh-Cuong LeRecommender systems are being widely applied in many fields, such as e-commerce, e-documents, places and travel, multimedia, news and advertising and transportation. These systems are similar to an information filtering system that helps to identify a set of items that best satisfy the users’ demands based on their preference profiles. The integration of contextual information (e.g., location, weather conditions and … …Journal of Computer Science, Vol. 18, Issue 3 · 28 Mar 2022 · 6,822 accessesView PDFCite
