Web information extraction for content augmentation
Proceedings. IEEE International Conference on Multimedia and Expo - Tập 2 - Trang 389-392 vol.2
A. Janevski, N. Dimitrova
Today, users have to cope with an overwhelming number of TV channels and Web content sources. We introduce automatic content augmentation as a novel approach to contextual information extraction on behalf of the user where the context is provided by the primary content source (i.e. TV channel) and tailored by the user's preferences. A key aspect of this approach is Web information extraction (WebI... hiện toàn bộ

Efficient and flexible drift-free video bitstream switching at predictive frames
Proceedings. IEEE International Conference on Multimedia and Expo - Tập 1 - Trang 541-544 vol.1 - 2002
Xiaoyan Sun, Shipeng Li, Feng Wu, Guobin Shen, Wen Gao
We propose an efficient and flexible coding scheme inspired by the SP picture technique in H.26L TML; it can achieve drift-free bitstream switching at predictive frames. Firstly, the proposed scheme improves the coding efficiency of the SP frames in H.26L TML by (1) reducing the number of quantization modules in the encoding path; (2) eliminating the mismatch between references for the prediction ... hiện toàn bộ

Human visual system features enabling watermarking
Proceedings. IEEE International Conference on Multimedia and Expo - Tập 2 - Trang 489-492 vol.2
J.F. Delaigle, C. Devleeschouwer, B. Macq, L. Langendijk
Digital watermarking consists of hiding subliminal information into digital media content, also called host data. It can be the basis of many applications, including security and media asset management. In this paper, we focus on the imperceptibility requirement for image watermarking. We present the main features of the human visual system (HVS) to be translated into watermarking technology. This... hiện toàn bộ

Audio mixing for centralized conferences in a SIP environment
Proceedings. IEEE International Conference on Multimedia and Expo - Tập 2 - Trang 269-272 vol.2
S. Hawwa
This paper focuses on centralized conferences in a session initiation protocol (SIP) environment and the different techniques deployed in audio mixing. We express the main issues in mixing audio over IP and discuss our own prototype as part of the multipoint control unit (MCU) implementation. We show measurements of our own implementation of audio mixing and present new features to be supported in... hiện toàn bộ

PDH: a human-centric interface for image libraries
Proceedings. IEEE International Conference on Multimedia and Expo - Tập 1 - Trang 901-904 vol.1
B. Moghaddam, Qi Tian, N. Lesh, Chia Shen, T.S. Huang
We present visualization and layout algorithms that can enhance informal story-telling using personal digital data such as photos in a face-to-face social setting. In order to build a more intuitive browser for retrieval, navigation and story-telling, we introduce a novel optimized layout technique for large image sets, which respects (context-sensitive) mutual similarities as visualized on a shar... hiện toàn bộ

A study on automatic database creation and summarization of a vaulting horse class
Proceedings. IEEE International Conference on Multimedia and Expo - Tập 2 - Trang 381-384 vol.2
H. Miyamori
This paper studies a method of automatically creating a database and effectively displaying a visual summary of a lesson, using content taken from a vaulting horse class. The study aims at establishing a content creation tool that can provide practical functions such as content-based retrieval and summarization, and content that can be shared by teachers and students over the network. The study al... hiện toàn bộ

Gaussian mixture model for relevance feedback in image retrieval
Proceedings. IEEE International Conference on Multimedia and Expo - Tập 1 - Trang 229-232 vol.1
Fang Qian, Mingjing Li, Lei Zhang, Hong-Jiang Zhang, Bo Zhang
Relevance feedback (RF) has become a powerful technique in content-based image retrieval. Most RF methods assume that positive images follow the single Gaussian distribution, which is not sufficient to model the actual distribution of images due to the gap between the semantic concept and low-level features. In this paper, the Gaussian mixture model (GMM) is applied to represent the distribution o... hiện toàn bộ

Repair options for 3-D wireframe model animation sequences
Proceedings. IEEE International Conference on Multimedia and Expo - Tập 1 - Trang 137-140 vol.1
S. Varakliotis, S. Hailes, J. Ostermann
To date, almost all work within the field of 3D animation has focused on raising perceptual appeal to an adequate level. However, it is a non-trivial task to match the requirements of real-time streams to the reality of the Internet. One of the key problems that must be addressed is that of how best to conceal errors in the event of packet loss. Thus we present the results of experiments designed ... hiện toàn bộ

Improving retrieval performance of Zernike moment descriptor on affined shapes
Proceedings. IEEE International Conference on Multimedia and Expo - Tập 1 - Trang 205-208 vol.1
Dengsheng Zhang, Guojun Lu
Shape (object) description consists a key part of image content description in MPEG-7. In the development of MPEG-7, Zernike moment descriptor (ZMD) has been adopted as region-based shape descriptor. However, because Zernike moments are defined in a unit disk and extracted from shape in polar space, less shape information is used for skewed and stretched shapes. As a result, the extracted ZMD is n... hiện toàn bộ

A motion-tolerant dissolve detection algorithm
Proceedings. IEEE International Conference on Multimedia and Expo - Tập 2 - Trang 225-228 vol.2
C.W. Su, H.R. Tyan, H.Y.M. Liao, L.H. Chen
Gradual shot change detection is one of the most important research issues in the field of video indexing/retrieval. Among the numerous types of gradual transitions, dissolve is considered the most common one, but also the most difficult to be detected one. It's well known that an efficient dissolve detection algorithm which can be executed on a real video is still deficient. In this paper, we pre... hiện toàn bộ
