Its representation is powerful enough to capture heterogeneous relationships among image entities. For CG they first oversegment the image into superpixels and find out different heterogeneous relationships among image entities (superpixels, vertices or junctions, edges, regions etc.) They construct the CG model with parameterization of links with derived Joint Probability Distribution (JPD). They represent these links by either potential function or conditional probabilities. They first create a Directed Master Graph then create directed sub-graphs for some terms in the

Any action that tailors the web experience to any individual or several users is termed as web personalization. Web personalization is that the method of customizing an internet website to the wants of specific users, taking advantage of the information noninheritable from the analysis of the user's guidance behaviour(Weblog data) in correlation with alternative data collected within the web context, namely, structure, content and user profile information. The domain of web personalization has gained importance both in the area of research and commerce. In this paper we proposed a framework of web log mining to implicit measures of user interests through Country and predicting users" future requests in WWW.

Many routing protocols were proposed which are categorized as proactive and reactive routing protocols. Route maintenance is a great challenge in MANET due to frequent link failure which causes high data loss and delay. To counter such problems, lots of link repair mechanisms were proposed, but all these have their own limitations. This paper proposes a novel routing algorithm for route maintenance based on link failure localization called DSR-LFL. DSR-LFL takes decision on the basis of location of failure link in source route. Proposed algorithm may improve the packet salvaging, delivery ratio and performance of DSR.

It is a new technology that satisfies a user’s requirement for computing resources like networks, storage, servers, services and applications, without physically acquiring them. It reduces the overhead of the organization of marinating the large system but it has associated risks and threats also which include – security, data leakage, insecure interface and sharing of resources and inside attacks.

Efficient and effective image segmentation is an important task in computer vision and object recognition. Since fully automatic image segmentation is usually very hard for natural images, interactive schemes with a few simple user inputs are good solutions. In this paper we presents image segmentation using similar region merging and comparison among different interactive image segmentation techniques. Segmentation should stop as object of interest in an application is isolated. The ultimate goal is to make the image more simplified and that to get more meaningful to analyze. This paper deals with the several segmentation techniques using human interactions models like PGM, Bayesian Networks Unified Graphical Models, Similar region merging etc., are taken from the literature are reviewed and a new interactive method...

One of the goals of organizations is to share their data and at the same time to enforce their policies. Web database is a combined production with database technology and Web technology. Web database is placed on the Internet, there are many security problems. The secrecy and the integrity are two important demands of security system. When database access control and the network security are addressed separately, the security systems are not optimized sufficiently as a whole. Finegrained access control (FGAC) must be supported by web relational databases to satisfy the requirements of privacy preserving and Internet-based applications. We propose a model of integrating network security with criterion based access control to handle network security and the fine grained Web database access control simultaneously. We have implemented our model in college database and performance is evaluated. Whenever any unauthorized user altered our data a system called Web-Secure report to the authorized user via E-mail or Short Message Service (SMS). The implementation results show that how our model is suitable for web database security.

Thus, the users are flooded with information. Due to this flooding, it is also important to see that right information may be provided to the right person at right time or 3R's, but many a times it does not happen. This paper studies various approaches by noted researchers, academician and their contributions to the multimedia retrieval systems. This paper also tries to bring out some pros and cons of the different approaches.
