In this paper, different types of speckle noise and impulse noise removal techniques are presented. Dual Tree complex wavelet transform because of having time and frequency resolution (MRA) and also of its shift invariance property works well in removing the speckle noise. Because of adaptive nature of mask size depending on the noise quantity in the image,(More)
With the development of cloud computing and internet; e-Commerce, e-Business and corporate world revenue are increasing with high rate. These areas not only require scalable and consistent databases but also require inter database transaction support. In this paper, we present, a scalable three-tier architecture along with a distributed middle-ware protocol(More)
Blocking methodologies sometimes fail to stop malicious things. Attacks on data oriented applications are a serious threat as per the database management systems concern. The required objective of such environment is to find out the mean time attacks and patch up the failures within the stipulated time. This manuscript represents a failure (attacked)(More)
The design of fragmentation is the first problem that must be solved in the design of data distribution. The purpose of fragmentation design is to determine nonoverlapping fragments which are logical units of allocation at different sites that are appropriate for the data allocation. For a distributed database system to function efficiently, the fragments(More)
