The use of firewalls to enforce access control policies can result in extremely complex
networks. Each individual firewall may have hundreds or thousands of rules, and when …

This paper suggests a discriminative approach for wavelet denoising where a set of
mapping functions (MFs) are applied to the transform coefficients in an attempt to produce a …

True estimation of the boundary of a road crack and its size is a major task for its automatic
detection. The improvement of visual effects of a road image is necessary for such a task …

Wavelet denoising is a classical and effective approach for reducing noise in images and
signals. Suggested in 1994, this approach is carried out by rectifying the coefficients of a …

Due to sparsity and multiresolution properties, Mutiscale transforms are gaining popularity in
the field of medical image denoising. This paper empirically evaluates different Mutiscale …

As an alternative to the wavelet, Gabor function has been used as an efficient representation
of two dimensional signals. We are interested in BayesShrink techniques for image …

Ultrasound imaging is one of the most important and cheapest instrument of the medical
imaging modalities. The quality of ultrasound imaging is degraded due to various types of …

The digital image carries a lot of pictorial information which has now become one of the chief
ways of communication in this generation. The transmission of media especially image is …

In this paper a combined Bayesshrink wavelet-ridgelet de-noising method is presented. In
our previous work we have showed that Bayesshrink ridgelet performs better than …
