In this paper, we propose a new classification scheme of MFCCs vectors in the context of speaker identification. The solution is built around the binary SVM classification between each speaker class and the background model class over the underlying spaces of the local independent components analysis using clustering. Experiments have been conducted on a sample of the MOBIO corpus.
For Radio Frequency Identification (RFID) system, this paper presents an anti collision circuit design for fast of multi tags identification system. Principally, the authors use the Blind Signal Separation (BSS) method by the Independent Component Analysis (ICA) algorithm based computation of anti-collision circuit for speedily extracting the hidden factor of signal independence in neural network...
Reliability and accuracy in personal identification system is a dominant concern to the security world. Biometric has gained much attention in this subject recently. Many types of personal identification systems have been developed, and palmprint identification is one of the emerging technologies. This paper presents a novel biometric technique to automatic personal identification system using multispectral...
Automatic personal identification using biometric information is playing a more and more important role in applications such as public security, access control, banking, etc. Palmprint identification is a subcategory of biometrics identification, which can efficiently used to identify the people. It is for this reason that palmprint-based identification is becoming increasingly popularity in recent...
Independent Component Analysis (ICA) based method for detection in the compound system MIMO-OFDM and in the context of CDMA is proposed. ICA algorithm is used as a post processor attached to a subspace based CDMA receiver. The proposed architecture of receiver reduces the bias caused by the channel noise and further decreases the noise by dimensionality reduction. A downlink CDMA based MIMO-OFDM channel...
When physically implemented, independent component analysis (ICA) algorithm can achieve a real time blind signal separation (BSS). However, due to the limited size of the hardware device in microelectronics technology, several constraints can be encountered to reach the real time processing since the application of the ICA algorithm requires the consumption of a huge number of input signal samples...
The application of independent component analysis (ICA) algorithm can achieve a real time blind signal separation (BSS) if it is physically implemented using hardware devices. However, due principally to both of the limited size and of the microelectronics technology of the used hardware devices, many practical problem can be encountered to reach the real time processing since the application of the...
We propose here a new method for POLSAR image analysis. The method is based on a new PCA-ICA model in which the relative Newton-based approach for performing ICA is developed. The basic idea of ICA with relative Newton method consists in approximating the negentropy by taking account of the orthogonality constraint of the extracted components. This concept is recognized for its robustness and gives...
To improve the performances of the wireless mobile communication system, a statistical method is illustrated in this paper. It consists in separating the signals at the reception of communication systems based on code division multiple access technology. The idea is to optimize the separation of the various users sharing the same frequency and temporal resources using the emergent statistical method...
The work presented here addresses the problem of the enhancement of the remote sensing image classification. For that, an evidential reasoning based classifier combination method is proposed. The originality of the work lies in the fact that the method treats the outputs of the classifiers by completely ignoring the internal characteristics of the latter. The method is thus general and applicable...
