Based on Eigenspace-Based (ESB) method, The paper presents a novel beamforming algorithm for the uniform linear array which constructs a special matrix instead of the covariance matrix. The algorithm can overcome the problem that ESB method cannot Work in the environment of coherent signals. Compared with the ESB using Toeplitz (TESB) technique, the new algorithm can work well in low SNR and small sample size. computer simulation results are presented and demonstrate the effectiveness of the proposed method. © 2004 IEEE.

An algorithm to compress 3D mesh sequences for dynamic objects is proposed in this work. Given an irregular mesh sequence, we construct a semi-regular mesh structure for the first frame and then map it to the subsequent frames based on the hierarchical motion estimation. The regular structure of the resulting mesh sequence enables us to employ the zero-tree coding scheme to compress the motion compensation residuals efficiently. Simulation results demonstrate that the proposed algorithm provides significantly better compression performance than the static coder that encodes each frame independently. © 2004 IEEE.

The capacity and performance of code division multiple access (CDMA) systems are limited by multiple access interference (MAI) and "nearfar" problem. Space-time multiuer detection combined with adaptive wavelet networks over frequency selective fading multipath channels is proposed in this paper. The structure of the multiuser detector is simple and its computational complexity mostly lies on that of wavelets networks. With numerical simulations and performance analysis, it is shown that the proposed detector can converge at the steady state rapidly and offer significant performance improvement over the space-time matched filtering detector, the conventional RAKE receiver and matched filter detector only at the time domain. Therefore, it can suppress the MAI and solve the "near-far" problem effectively. © Springer-Verlag Berlin Heidelberg 2004. All rights reserved.

With dynamics property and highly parallel mechanism, recurrent neural networks (RNN) can effectively implement blind adaptive multiuser detection at the circuit time constant level. In this paper, the RNN based blind adaptive multiuser detection is extended to ubiquitous asynchronous DSCDMA systems, and the performance of the output signal to interference plus noise ratio, asymptotic multiuser efficiency, computational complexity, operating time, and mismatch of the detector are quantitatively analyzed. With performance analysis and numerical simulations, it is shown that RNN based blind adaptive multiuser detection can converge at the steady quickly and offer significant performance improvement over some existing popular detectors in eliminating multiple access interference and "near-far" resistance. © Springer-Verlag Berlin Heidelberg 2004.

This paper outlines the automatic extraction of features of paintings' art movements such as classicism, impressionism and cubism;and introduces a system developed for the classification and indexing of paintings based on their art movements. A six dimensional feature set is proposed for the representation of content and it is shown that the feature set enables to highlight art movements efficiently. In the classifier design, statistical pattern recognition approach is exploited and Bayesian, k-NN and SVM classifiers are employed. A classification accuracy of over 90% is achieved with very small false alarm ratios while the lowest performance is obtained by the k-NN. System also offers a quick query based database search by indexing the paintings with their six dimensional feature vectors, and provides an applicable program for museums and exhibition centres. © 2004 EUSIPCO.

We address a problem to reconstruct the original signal with lost data by using FIR synthesis filters in a class of linear-phase perfect reconstruction (PR) oversampled filter banks (FB) called lapped pseudo-orthogonal transform (LPOT), which belongs to a class of overcomplete linear-phase paraunitary FB's, in which the synthesis filters are given as the paraconjugate of the analysis filters. When some subband coefficients are lost, the use of the Moore-Penrose pseudo-inverse of the analysis FB can achieve PR, but the corresponding synthesis filters can have IIR. We firstly discuss the possibility of PR with FIR filters of the same length as the analysis filters, and show the synthesis filters which can optimally suppress additive noise in some sense. We then show an example of the resulting synthesis filters. Finally, we suggest some open problems. © 2004 EUSIPCO.

European signal processing Conference (EUSIPCO)

作者： Ramin Pichevar Jean Rouat Christian Feldbauer Gernot Kubin Dept. of Elect. and Computer Eng. University of Sherbrooke Sherbrooke QC Canada Universite de Sherbrooke Sherbrooke QC CA Signal Processing and Speech Comm. Lab. Graz University of Technology Graz Austria

A sound source separation technique based on a two-layered bio-inspired spiking neural network and an enhanced gammatone analysis/synthesis filterbank is proposed. One of the two bio-inspired proposed spectral maps (Cochleotopic / AMtopic or Cochleotopic / Spectrotopic) is used as a front-end to the neural network depending on the nature of the intruding sound. We show that the use of an FIR gammatone filterbank outperforms the previous results obtained by using an IIR gammatone cochlear filterbank, since the FIR implementation has near-perfect reconstruction ability and the cascade of the analysis and synthesis filterbanks is linear-phase.

Reconfigurable coprocessor for media streaming

Reconfigurable coprocessor for media streaming

IEEE International Conference on Multimedia and Expo (ICME)

作者： S. Bilavarn E. Debes Signal Process. Lab. Swiss Fed. Inst. of Technol. Lausanne Switzerland Signal Processing Institute Swiss Federal Institute of Technology Lausanne Switzerland Architecture Research Labs Intel Corporation Santa Clara CA

The development of more processing demanding video standards on one hand and the popularity of mobile devices such as digital cameras or wireless videophones on the other hand introduce a need of optimization at the processor level. Reconfigurable systems provide an interesting answer to this problem and several works have explored the possibility of performance and power optimization. The following study focuses on tuning a reconfigurable hardware to the requirements of future media processing, using DSP operators appearing in recent FPGA families as an alternative to the typical ALU based architectures. In this paper, architecture perspectives are proposed with respect to low cost development constraints, backward compatibility, easy coprocessor usage and power / performance enhancement, using a new scalab.e data representation optimized for quality of service (matching pursuit 3D algorithms).

Linear Predictive method with Low-Frequency Emphasis 8

Linear Predictive method with Low-Frequency Emphasis

引用

8th European Conference on Speech Communication and technology, EUROSPEECH 2003

作者： Alku, Paavo Bäckström, Tom Lab. of Acoustics and Audio Signal Processing Helsinki University of Technology Finland

An all-pole modeling technique, Linear Prediction with Low-frequency Emphasis (LPLE), which emphasizes the lower frequency range of speech, is presented. The method is based on first interpreting conventional linear predictive (LP) analyses of successive prediction orders with parallel structures using the concept of symmetric linear prediction. In these implementations, symmetric linear prediction is preceded by simple pre-filters, which are of either low or high frequency characteristics. Combining those symmetric linear predictors that are not preceded by high-frequency pre-filters yields the LPLE predictor. It is proved that the all-pole filters computed by LPLE are always stable. The results show that the method is well-suited when low-order all-pole models with improved modeling of the lowest formants are needed.
