A new subspace approach is proposed for enhancement of image corrupted by additive white noise. In subspace filtering methods, the noisy image is decomposed into two orthogonal subspaces, a signal subspace and a noise subspace. This decomposition is possible under the assumption of a low-rank model for image and the availability of an estimate of the noise covariance matrix. It is shown in this paper...
In order to ameliorate the degree of trustiness and, high security, we have presented a new approach to hand signature verification applying data glove. Data glove is a new-fangled dimension in the field of virtual-reality environments, originally designed to satisfy the stringent requirements of modern motion capture and animation professionals. In our research, we attempt to change over the carrying...
A novel OFDM system based on dual - tree complex wavelet transform (DTCWT) is proposed in this work. The proposed scheme offers the best PSD and BER performance than the conventional OFDM and wavelet packet modulation (WPM) systems at the expense of acceptable computational complexity without using any pruning techniques. The need for CP is eliminated in the system design due to the good orthogonality...
