In this paper we present two algorithms for information extraction from Single Look Complex (SLC) Synthetic Aperture Radar (SAR) images. The first algorithm is based on Tikhonov regularization with Total Variation (TV) and a Point-Based Feature (PBF) term. Based on the equivalence of Tikhonov and the Bayesian estimate, the second algorithm is a Maximum A Posteriori (MAP) estimation with a complex-valued Gauss-Markov Random Field (GMRF) in addition to the TV prior. The first algorithm produces a despeckled image preserving fine details and texture. The second algorithm gives a denoised image and in addition the estimated feature parameter vector θ. © 2008 IEEE.

Near infared spectroscopy (NIRS) is a non-invasive method to measure the brain activity as the changes of hemoglobin oxygenation through the intact skull. In this paper, we statistically analyze the NIRS data based on general linear model (GLM) and propose a new theory for making inference using Sun's tube formula. More specifically, we calculate the p-values as the excursion probability of an inhomogeneous Gaussian random field on a two dimensional representation manifold that are dependent on the structure of error co variance matrix and the interpolating kernels. These powerful tools for excursion probability allows us the super-resolution localization of the brain activation which is not possible using the conventional NIRS analysis.

A model based approach called k-t BLAST/SENSE, has drawn significant attentions from MR imaging community due to its improved spatio-temporal resolution. Recently, we showed that k-t BLAST/SENSE corresponds to the special case of a new dynamic MRI algorithm called k-t FOCUSS that is asymptotically optimal from compressed sensing perspective. The k-t FOCUSS exploits the sparsity of x-f support of dynamic scene and converts imaging problem into an L 1 minimization problem that can be solved using FOCal Underdetermined System Solver (FOCUSS). In this paper, we extend the idea of k-t FOCUSS and introduce motion estimation and compensation (ME/MC) based prediction step and residual encoding step. The ME/MC based prediction step exploits the temporal redundancies using the motion field estimation and provides much sparser residual signals. The sparse residual signal can then be effectively encoded using much smaller number of k-t samples. Simulation results demonstrate that high resolution dynamic MR images can be accurately obtained even from very limited data samples.

While direct association rules are dedicated to describe the direct correlations among the items in a frequent itemset, indirect association rules are dedicated to describe the indirect correlations between the two items in a infrequent itemset. All the existing research works about indirect association rules are focused on improving the efficiency of mining algorithm for indirect association rules. Like incremental updating algorithm is important for mining association rules, incremental updating algorithm is also important for mining indirect association rules. In this paper, we put forward an incremental updating algorithm for mining indirect association rules to deal with the maintenance of discovered indirect association rules resulted from the change of the minimum support. The main idea is to re-utilize the results acquired in process with the old minimum support.

IEEE International Symposium on Biomedical Imaging

作者： Rafal Zdunek Zhaoshui He Andrzej Cichocki Institute of Telecommunications Teleinformatics and Acoustics Wroclaw University of Technology Wroclaw Poland Laboratory for Advanced Brain Signal Processing RIKEN Brain Science Institute Saitama Japan

In tomographic image reconstruction from limited-view projections the underlying inverse problem is ill-posed with the rank-deficient system matrix. The minimal-norm least squares solution may considerably differs from the true solution, and hence a priori knowledge is needed to improve the reconstruction. In our approach, we assume that the true image presents sparse features with uniform spacial smoothness. The sparsity constraints are imposed with the lscr p diversity measure that is minimized with the FOCUSS algorithm. The spacial smoothness is enforced with the adaptive Wiener noise removing implemented in each FOCUSS iterations. The simulation results demonstrate the benefits of the proposed approach.

International Conference on signal processing and Communication Systems, ICSPCS

Adaptive modulation schemes have been proposed to optimize Shannon's channel capacity in recent orthogonal frequency division multiplexing (OFDM) based broadband wireless standard proposals. By adapting the modulation type (effectively changing the number of bits per symbol) at the transmitter end one can improve the bit error rate (BER) during transmission at designated SNR. blind detection of the transmitted modulation type is desirable to optimise the bandwidth available at the receivers. Hence, there is a need for an intelligent modulation classification engine at the receiver end. In this work, we evaluate some higher order statistical measures coupled with a classical Naive Bayes classifier for fast identification of adaptive modulation schemes. We also benchmark the experimental results with the optimal Maximum Likelihood Classifier, and Support Vector Machine based Classifier using the same feature set.

Recently, Han-Chang showed that Xiao-Liao-Deng's key agreement protocol based on chaotic maps is vulnerable to man-in-the-middle attack and proposed two improved schemes. One works in clock synchronization, and the other can work without synchronization. They claimed that their schemes are secure against replaying attacks and can establish a shared session key. However, we point out that all the aforementioned schemes are Non-contributory, i.e. the malicious party can predetermine the shared session key by the vice of several Chebyshev polynomials passing through the same point. In particular, we demonstrate that the asynchronous key agreement protocol can't resist replaying attack. Therefore, the use of these schemes for secure applications may be discouraged.

IEEE International Conference on Networking, Sensing and Control

It is well-known that finding paths with minimum hop count leads to poor performance in wireless mesh networks (WMN) because the assumption of the same transmission failure probability in all links may not be true. A routing metric can assist traditional routing protocol in selecting better paths by explicitly taking the interference, delay etc. into account. This paper presents a thorough review and a comparison of 10 kinds of routing metrics designed for diverse QoS requirements in WMN. Meanwhile, this paper classifies these routing metrics into three basic types, ETX-based metrics, mETX, and some other metrics less attractive to WMN routing layer, for better understanding and future applications. To the best of our knowledge, no paper except this one has such a comprehensive review of routing metrics utilized in WMN.

The expectation-maximization (EM) algorithm is a popular approach for parameter estimation of finite mixture model (FMM). A drawback of this approach is that the number of components of the finite mixture model is not known in advance, nevertheless, it is a key issue for EM algorithms. In this paper, a penalized minimum matching distance-guided EM algorithm is discussed. Under the framework of Greedy EM, a fast and accurate algorithm for estimating the number of components of the Gaussian mixture model (GMM) is proposed. The performance of this algorithm is validated via simulative experiments of univariate and bivariate Gaussian mixture models.
