The proposed approach of this paper is based on integration of the local weighted Markov Random Fields (MRF) on support vector machine (SVM) framework for hyperspectral spectral-spatial classification. Our proposed method consists of performing probabilistic SVM classification followed by a spatial regulation based on the MRF. One important innovation of(More)
This paper proposes some novel classification scheme based on adaptive spatial vicinity for hyperspectral remote sensed images. Different segmentation methods such as Robust Color Morphological Gradient (RCMG), Expectation Maximization (EM) and Recursive Hierarchical Segmentation (RHSEG) have been generalized to hyperspectral image analysis and their(More)
In this paper, several criteria to measure the nonuniform distribution of the spatial-spectral information were investigated in hyperspectral remotely sensed images, then a novel weighted spatial-spectral kernel is introduced. They are proportional to combined (linear / constrained linear and nonlinear) distance measures. Then, the extracted weight vector(More)
This paper has mentioned new algorithms in adaptive acoustic echo cancellation (AEC): subband adaptive filtering (SAF) and partitioned block Hartley domain adaptive filtering (PBHDAF). The computational complexity of these algorithms is less than their older partners with very fast convergence rate. We have proposed these algorithms for real time processing(More)
Subband adaptive filtering has attracted much attention lately. In this paper, a new and improved structure and a new formulation for adapting the filter coefficients is discussed. The scheme is based on infinite impulse response (IIR) filterbanks, formed from allpass polyphase filters, which exhibit very high quality filtering compared to typical finite(More)
We consider a spherical thick 3-brane immersed in a five-dimensional bulk spacetime. We demonstrate how the thick brane equation of motion expanded in powers of the thickness of the brane can be obtained from the expected junction conditions on the boundaries of thick brane with the two embedding spacetimes. It is shown that the finite thickness leads to a(More)
