However, land mine detection still remains a difficult task because of the changing conditions and the strong reflection of the ground. In this paper, a generalized two-sided linear prediction model is used to estimate the background. By effectively removing the background components from the GPR signal, the residual energy is found to be more reliable to generate the test statistic for detection. Results based on real GPR data show that the proposed method is able to not only remove the ground bounce and background signal but also suppress the response from some clutter objects.","PeriodicalId":176384,"journal":{"name":"2007 15th European Signal Processing Conference","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123488550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the presence of background disturbances, the registered real-life signals contain a mixture of a source signal (emitted by the vehicle), and a corrupting signal (narrow-band “background noise” of bandwidth similar to the original signal). A new method of the background noise elimination is proposed in this paper. The method is based on the lattice-structured Schur-type orthogonalization/parametrization algorithms in which the so-called backward estimation errors, computed for the incoming signal, constitute an orthonormal basis. The proposed solution employs the orthogonal joint-process estimation filter which decomposes the incoming signal using an orthonormal basis, derived exclusively for the background noise. The effectiveness of the method is discussed as well as the noise cancellation results, also using real-life signals, are presented.","PeriodicalId":176384,"journal":{"name":"2007 15th European Signal Processing Conference","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121661550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This necessitates a flexible and dynamic resource reallocation, where the assumed traffic is unsymmetrical, i.e. the number and bandwidths of incoming and outgoing FDM signals are unequal. This paper details the SISO SBC-FDFMUX filter bank based on critically sampling Modified DFT (MDFT) filter banks and extends it to critically sampling symmetrical MIMO MDFT SBC-FDFMUX systems. The paper concludes with simulation results showing the potential of this filter bank approach for flexible frequency reallocation.","PeriodicalId":176384,"journal":{"name":"2007 15th European Signal Processing Conference","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123296252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For instance, the laser-extinction measurements (LEM) use a laser beam passing across the fluid and measure the residual laser light intensity at the fluid output. Some particle and fluid properties are estimated from these measurements such as concentration or velocity. However, the flow is submitted to fluctuations. The received intensity is more appropriately modeled by a random process. This paper first models the particle flow by a queueing process. The measured intensity statistics are derived according to this model. A particular case is the scintillation index which is independent of the emitted intensity. The proposed model allows to define higher order scintillation indices with the same property. Alternative estimates of the fluid and particle properties can be deduced from these quantities.","PeriodicalId":176384,"journal":{"name":"2007 15th European Signal Processing Conference","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131442177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For frequency selective fading - i.e. dispersive - MIMO channels, solutions in the literature are fewer, and are in their majority block based, such as MIMO OFDM or time-reversal STBC. In order to ultimately achieve better tracking behaviour, in this paper we focus on the development of a non-block-based method. We utilise a constant modulus criterion on the detected signals together with the orthogonality contraint of the transmitted STBC signals, whereby for the later we derive novel criterion and an adaptive optimisation scheme. We demonstrate the proposed system in simulations and compare it to the performance of a TRSTBC system.","PeriodicalId":176384,"journal":{"name":"2007 15th European Signal Processing Conference","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130418647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the second step, Principal Components Analysis (PCA) and Kernel PCA(KPCA) were applied to each class for extracting principal features of beauty. Support Vector Machine (SVM) was used for judging whether a given face is beautiful or not. Since judging the beauty is subjective, the decision results of our system were evaluated by comparing the system generated decision results with the corresponding ones made by the persons. Based on this criteria, our results showed that KPCA with a success ratio of 89% outperformed PCA with a success ratio of 83%.","PeriodicalId":176384,"journal":{"name":"2007 15th European Signal Processing Conference","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130386801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, these DSC-based video encoders are usually characterized by a lower compression gain with respect to their hybrid counterparts. In this work, we investigate achieving H.264-like high compression efficiency with a DSC-based approach without constraints on encoding complexity. In this way, highly non-stationary video data are modelled through coarse low-cost Motion Estimation, and this allows us to obtain a good compression efficiency together with a certain robustness to channel errors and losses. Experimental results show that in presence of losses the presented algorithm permits a better quality with respect to H.264/AVC.","PeriodicalId":176384,"journal":{"name":"2007 15th European Signal Processing Conference","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116442191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
