We enhance the popular k-means clustering algorithm to integrate user-supplied domain-knowledge into the cluster generation step. This provides a convenient way to exclude scenes from the summary which are a-priori known to be irrelevant. Furthermore, we added an additional, time-constrained clustering step preceding the scene clustering step to exclude short ranges with transitional content. This makes the algorithm robust to fading and wipe-effects in the input without requiring explicit cut detection.","PeriodicalId":90694,"journal":{"name":"Proceedings.

Since 3D mesh models often have the huge amount of the data, it is time-consuming to retrieve from a storage device or to download from the network. Most 3D viewing applications need to obtain the entire file of a 3D model in order to display the model, even when the user is interested only in a low-resolution version of the model. Therefore, progressive coding that enables multiresolution transmission of 3D models is desired. We propose the progressive coding scheme of 3D meshes with texture, in which we convert irregular meshes to semiregular using texture coordinates, map them on planes, and apply 2D image coding algorithm to mesh compression. As our method uses the wavelet transform, the encoded bitstream has a progressive nature. We gain high compression rate with the same visual quality as original models.","PeriodicalId":90694,"journal":{"name":"Proceedings.

We focus on finding off-line optimal rate control for VBR transmission with a token bucket policing function. To ensure a maximum minimum quality is obtained over all data units, we introduce a minimum maximum distortion (MMAX) criterion in this channel-constrained problem. We show that, due to the channel constraints, a MMAX solution leads to a relatively low average distortion, because the total rate budget is not completely utilized. Therefore, after finding a MMAX solution, an additional minimization of average distortion (MMAX+) criterion is proposed to increase overall quality of the data sequence by using remaining resources. The proposed algorithms lead to an increase in average quality with respect to the MMAX solution, while providing a much more constant quality than MMSE solutions. Moreover we show how the MMAX+ approach can be implemented with low complexity.","PeriodicalId":90694,"journal":{"name":"Proceedings.

The proposed method is based on the design and the implementation of integer wavelets. Instead of using the lifting scheme or sacrificing vanishing moment to obtain integer coefficients, the proposed method derives integer coefficients directly from roots of the half band filter. Based on the integer filter coefficients, we propose an efficient VLSI algorithm, which uses only 17 integer adders and 15 shifters to construct a two-channel filter bank system. The complexity of the proposed method is significantly lower than that found in the convolution and lifting approaches. The convolution approach requires 9 floating-point multiplications and 14 floating-point additions. Likewise, the lifting scheme needs 6 floating-point multiplications and 12 floating-point additions. Besides the mathematical derivation, this paper presents simulation results, which compare the frequency responses and coding efficiency between the floating-point and the integer approaches. In addition, a VHDL implementation result is presented.","PeriodicalId":90694,"journal":{"name":"Proceedings.

This assumption becomes an important limitation when studying input from real systems. We present a new approach to robustly determine face expressions independently of the head pose. Our analysis-synthesis cooperation, possible thanks to the use of a highly realistic 3D head model and the application of Kalman filtering to predict the user pose, permits us to correctly track the interesting face features. Adapting 'near-to-front' analysis techniques based on the predicted pose enables us to use such algorithms with moving speakers.","PeriodicalId":90694,"journal":{"name":"Proceedings.

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 and the reconstruction; (3) outputting a high quality image for display purpose before the quantization step in the reconstruction loop. Secondly, the proposed scheme allows independent quantization parameters for up-switching and down-switching bitstreams. It can further reduce the switching bitstream size while keeping the coding efficiency of the normal bitstreams. It allows more rapid and frequent down-switching than up-switching. Furthermore, the size of the down-switching bitstream can be much smaller than that of the up-switching one. This is a very desirable feature for any TCP-friendly protocols currently used in most existing streaming systems.","PeriodicalId":90694,"journal":{"name":"Proceedings.

As a satellite interactive education material providing system, the ISRE system has a requirement of low bit rate transmission of video lecture screen. To achieve this goal, we used MPEG-4 video tools instead of the conventional MPEG-2 solution. The design is mainly concentrated on the transmission framework of the MPEG-4 stream and the real-time implementation of the MPEG-4 video codec that has live casting and offline MP4 file casting capabilities. The ISRE real-time MPEG-4 codec was implemented by using multimedia extended software techniques such as code optimization, MMX programming and DirectX/spl trade/ programming without using any dedicated hardware. Concerning the transmission framework, we used the DVB MPE and data carousel protocol for the casting and MP4 file clip transmission so as to ensure the delivery of educational materials.","PeriodicalId":90694,"journal":{"name":"Proceedings.
