We first demonstrate a representation based on a template-frequency model (TFM) that allows the full use of the temporal dimension.

Forward and backward signal propagation is the key in this automatic relevance feedback method in order to enhance retrieval accuracy.","PeriodicalId":118560,"journal":{"name":"2003 International Conference on Multimedia and Expo.

In this paper a novel architecture for real-time betting is presented. It disposes of the up-front effort and enables frequent bet announcements and placements during an ongoing event. The novel situation is achieved by broadcasting announcements, time-stamping and storing the placements locally, and collecting them after the event has been finished. While solving the processing problems, the architecture requires reliable cryptographic and physical protection. Currently, e.g. DVB and LAN technologies offer potential platforms for providing the service. The implemented LAN demonstrator has shown that user interfaces have to be simple and bets should not be announced too often. It has also shown that real-time operation makes betting more inspiring.","PeriodicalId":118560,"journal":{"name":"2003 International Conference on Multimedia and Expo. ICME '03. Proceedings (Cat.

The algorithm is based on spatial correlation of motion vectors and yields good tradeoff between motion estimation distortion and number of SAD computations. The speed up achieved by the algorithm is in the order of 190-280 times and the SAD increase is 2-10% compared to full search. The number of bits required to code motion vectors is less as the algorithm is based on correlation of motion vectors. Overall performance of the algorithm is compared with full search and three-step search using speed-up, average SAD per macroblock (MB), motion vector bits per MB and PSNR as objective measure. The proposed algorithm can be used in standards such as MPEG-2, MPEG-4 ASP, etc. The proposed algorithm is implemented in our MPEG-2 encoder and performance of the algorithm is presented for the same.","PeriodicalId":118560,"journal":{"name":"2003 International Conference on Multimedia and Expo.

We briefly overview algorithms for obtaining, manipulating and inverting cortical representation of sound and describe algorithms for manipulating signal pitch and timbre separately. The algorithms are first used to create sound of an instrument between a guitar and a trumpet. Applications to creating maximally separable sounds in auditory user interfaces are discussed.","PeriodicalId":118560,"journal":{"name":"2003 International Conference on Multimedia and Expo.

Our approach is to compute the dimensions of objects represented by the unit vector of objects from an image. The dimension vector v can be solved by the standard nonlinear optimization techniques with a multistart method which generates multiple starting points for the optimizer by sampling the parameter space uniformly. This method allows model-based vision to be computed for the dimensions of object for a 3D model from matches to a single 2D image. Experimental results show the actual dimensions of object from an image agree well with the calculated results.","PeriodicalId":118560,"journal":{"name":"2003 International Conference on Multimedia and Expo.

Two methods are propagated and compared throughout the paper. Within the first method a global statistics framework of an utterance is classified by Gaussian mixture models using derived features of the raw pitch and energy contour of the speech signal. A second method introduces increased temporal complexity applying continuous hidden Markov models considering several states using low-level instantaneous features instead of global statistics. The paper addresses the design of working recognition engines and results achieved with respect to the alluded alternatives. A speech corpus consisting of acted and spontaneous emotion samples in German and English language is described in detail. Both engines have been tested and trained using this equivalent speech corpus. Results in recognition of seven discrete emotions exceeded 86% recognition rate. As a basis of comparison the similar judgment of human deciders classifying the same corpus at 79.8% recognition rate was analyzed.","PeriodicalId":118560,"journal":{"name":"2003 International Conference on Multimedia and Expo.

The method consists of range data registration and comparison. There are two steps in registration procedure: the coarse step conducting the normalization by exploiting a priori knowledge of the human face and facial features, and the fine step aligning the input data with the model stored in the database by the partial directed Hausdorff distance. To speed up the registration, a simplified version of the model is generated for each model in the model database. During the face comparison, the partial Hausdorff distance is employed as the similarity metric. The experiments are carried out on a database with 30 individuals and the best EER of 3.24% is achieved.","PeriodicalId":118560,"journal":{"name":"2003 International Conference on Multimedia and Expo.
