-In this paper the technique for resolution and contrast enhancement of satellite geographical images based on discrete wavelet transform (DWT), stationary wavelet transform (SWT) and singular value decomposition (SVD) has been proposed. In this, the noise is added in the input low resolution and low contrast image. The median filter is used remove noise from the input image. This low resolutio...

no trace of the wild talk to which some of his followers have accustomed us. To demand " millions of houses " in the twinkling of an eye is to cry for the moon. If thousands of millions of money were available for the purpose to-morrow the thing could not be done. Men are as essential as money, and men at present are not forthcoming. It is true that the'Prime Minister is sanguine of being able,...

In addition to coil sensitivity data (parallel imaging), sparsity constraints are often used as an additional lp-penalty for under-sampled MRI reconstruction (compressed sensing). Penalizing the traditional decimated wavelet transform (DWT) coefficients, however, results in visual pseudo-Gibbs artifacts, some of which are attributed to the lack of translation invariance of the wavelet basis. We...

Resolution and contrast are the two important attributes of an image. In this paper we developed a method to enhance the quality of the given image. The enhancement is done both with respect to resolution and contrast. The proposed technique uses DWT and SVD. To increase the resolution, the proposed method uses DWT and SWT. These transforms decompose the given image into four sub-bands, out of ...

It is difficult to accurately reckon vehicle position for vehicle navigation system (VNS) during GPS outages, a novel prediction algorithm of dead reckon (DR) position error is put forward, which based on Bayesian regularization back-propagation (BRBP) neural network. DR, GPS position data are first denoised and compared at different stationary wavelet transformation (SWT) decomposition level, ...

Mammograms are one of the most widely used techniques for preliminary screening of breast cancers. There is great demand for early detection and diagnosis of breast cancer using mammograms. Texture based feature extraction techniques are widely used for mammographic image analysis. In specific, wavelets are a popular choice for texture analysis of these images. Though discrete wavelets have bee...

We give the geometric version of a construction Colmez-Niziol which establishes comparison theorem between arithmetic p-adic nearby cycles and syntomic sheaves. The local period isomorphism uses $(\phi,\Gamma)$-modules theory is obtained by reducing to cohomologies Lie algebras. By applying method "more general coordinates" used Bhatt-Morrow-Scholze, we construct global isomorphism. In particul...
