Simple uniform quantization disregards the spatial information among pixels in making histograms. Since traditional vector quantization (VQ) with squared-error distortion employs only the first moment, it neglects the relationship among vectors. We propose Gauss mixture vector quantization (GMVQ) as the quantization method for a histogram-based image retrieval to capture the spatial information in the image via the Gaussian covariance structure. Two common histogram distance measures are used to evaluate the similarity of histograms resulting from GMVQ. Our result shows that GMVQ with a quadratic discriminant analysis (QDA) distortion outperforms the two typical quantization methods in the histogram- based image retrieval.","PeriodicalId":118560,"journal":{"name":"2003 International Conference on Multimedia and Expo.

This constraint specifies the maximum data rate that can be transmitted reliably with QoS (quality of service) guarantee. In our framework, the time-varying service channel is modeled by an N-state discrete Markov process, where each Markov state is associated with a channel service rate, and the absolute priority scheduling is used to transport packets of different classes. The transmission rate constraint is derived based on effective bandwidth and capacity. To be more specific, given channel parameters and the maximum buffer size for each priority class, statistical QoS guarantees in terms of packet loss probabilities can be determined and translated to the transmission rate constraint. The derived result is verified by simulation in a time-varying wireless environment.","PeriodicalId":118560,"journal":{"name":"2003 International Conference on Multimedia and Expo. ICME '03.

However, in the real applications, face appearance changes significantly due to different illumination, pose, and expression. Face recognizers based on different representations of the input face images have different sensitivity to these variations. Therefore, a combination of different face classifiers which can integrate the complementary information should lead to improved classification accuracy. We use the sum rule and RBF-based integration strategies to combine three commonly used face classifiers based on PCA, ICA and LDA representations. Experiments conducted on a face database containing 206 subjects (2,060 face images) show that the proposed classifier combination approaches outperform individual classifiers.","PeriodicalId":118560,"journal":{"name":"2003 International Conference on Multimedia and Expo.

In cinematic theory, lighting design plays an important role in illumination, directing viewer's gaze to important locations, and portraying visual tension. However, lighting design is a complex process, and is especially problematic for interactive entertainment systems, since important design parameters such as spatial configuration, dramatic focus, and dramatic intensity, cannot be determined in advance. Indeed, they often change dramatically during interaction. Additionally, manually adjusting colors, positions, and angles of each light in a scene is a time consuming and tedious process. In this paper, we describe a system developed based on cinematic and theatrical lighting design theory to automatically adjust positions, colors, and angles of each light in real-time to accommodate the continually evolving dramatic situation, while maintaining the desired style, and ensuring visual continuity.","PeriodicalId":118560,"journal":{"name":"2003 International Conference on Multimedia and Expo.

The proposed method is, in effect, a way of measuring the amount of blurring in the image.

In our authentication scheme we consider three common video transcoding methods as acceptable content manipulations, when the streaming bit-rate needs to be reduced, namely frame resizing, frame dropping and multi-cycle coding. By employing error correction coding (ECC) in different ways, the proposed scheme is insensitive to those incidental distortions introduced during the transcoding (i.e., robust) while is still sensitive to other intentional distortions such as frame alterations and insertion (i.e., secure). One key feature in our scheme is that it achieves an end-to-end authentication independent of transcoding infrastructure and obtains a good compromise between system robustness and security.","PeriodicalId":118560,"journal":{"name":"2003 International Conference on Multimedia and Expo.

The perception of the world reflected through a mirror depends on the viewer's position with respect to the mirror and the 3-D geometry of the world. In order to simulate a real mirror on a computer screen, images of the observed world, consistent with the viewer's position, must be synthesized and displayed in real- time. Our system is build around a LCD screen manipulated by the user, a single camera fixed on the screen, and a tracking device. The continuous input video stream and tracker data is used to synthesize, in real-time, a continuous video stream displayed on the LCD screen. The synthesized video stream is a close approximation of what the user would see on the screen surface if it were a real mirror.

Specifically, we examine the possibility to use object- based coding for efficient long-term archiving of surveillance video. We consider surveillance systems with many camera sources in which we are required to store several months of video data for each source, thus storage capacity is a major concern. The paper considers several automatic segmentation algorithms. With each algorithm, we analyze the shape coding overhead and implication on overall storage requirements, as well as the effect each algorithm has on the reconstructed quality of frames. Additionally, this paper reviews techniques to dynamically control the temporal rate of objects in the scene and perform bit allocation. Experimental results show that up to 90% savings in storage can be achieved with the proposed method compared to frame-based video coding techniques. The cost for this savings is that the accuracy of the background is compromised; however, we feel that this is satisfactory for the application under consideration.","PeriodicalId":118560,"journal":{"name":"2003 International Conference on Multimedia and Expo.
