As a result of noise and intensity non-uniformity, automatic segmentation of brain tissue in magnetic resonance imaging (MRI) is a challenging task. In this study a novel brain MRI segmentation approach is presented which employs Dempster-Shafer theory (DST) to perform information fusion. In the proposed method, fuzzy c-mean (FCM) is applied to separate… (More)
In this paper a new approach for speech enhancement is presented. The proposed algorithm is based on singular value decomposition (SVD) and wavelet transform. A model of contaminant noise is estimated by using SVD in the recommended method and then, using of noise estimation determines thresholding value. Needlessness of silence frame in order to estimate… (More)
Chaotic behavior and control of Genesio-Tesi and Coullet is studied, in this paper. The Sliding Mode Control is proposed for synchronization in a pair of topologically inequivalent systems, the Genesio-Tesi and Coullet systems. The simulation result verifies the effectiveness of the proposed method.
