Abstract: An occlusion is the region between two overlapping objects with disparate motion. Detecting these occluded objects is crucial for many of the video processing. The Occlusion detection is decomposed into two independent sub problems. The First is to detect foreground objects on a frame-wise basis, by labeling each pixel in an image frame as either foreground or background. The second is to couple object observations at different points in a sequence to yield the object's motion trajectory and Occlusion. The motion segmentation is based on an adaptive background subtraction method that models each pixel as mixture of Gaussians. The Gaussian distributions are then evaluated to determine which are most likely to result from a background process. This is useful to track moving objects and detect occlusion in lighting changes, repetitive motions from cluster, and long term scene changes.

Title : Latent Fingerprint Matching Using Grey Level Co-Occurrence Matrix

Abstract: Recognizing defendant based on impressions of fingers from crime scenes is important to law enforcement agencies. Latents are partial fingerprints with small area, contain nonlinear distortion,and are usually dirty and less distinct. Due to some of these characteristics, they have a seriously smaller number of minutiae points and thus it can be distinctly difficult to automatically match latents to plain or rolled fingerprints that are stored in law enforcement databases. The goal is to develop a latent matching algorithm that uses only minutiae information. The proposed algorithm uses a robust alignment algorithm (descriptorbased Hough transform) to align fingerprints and measures similarity between fingerprints by considering both minutiae and orientation field information.Since the proposed algorithm depend only on manually marked minutiae, it can be easily used in the law enforcement application.We can added an texture feature to improve the matching performances by using a method called gray-level co-occurrence matrix.The texture features are contrast,correlation,energy and homogeneity.The proposed approach consists of following three modules: (i) align two sets of minutiae by using a descriptor-based Hough Transform; (ii) establish the correspondences between minutiae; and (iii) compute a similarity score.

Abstract: Mobile phones are among the most popular consumer devices, and the recent development of 3G networks, rapidly increasing power of personal mobile devices (smart phones, tablets, etc.) is providing much richer contents and social interactions to users. This trend however is restricted by the limited battery lifetime of mobile devices and unstable wireless connectivity, making the highest possible quality of service experienced by mobile users not feasible .The recent cloud computing technology, with its rich resources to compensate for the limitations of mobile devices and connections, can potentially provide an ideal platform to support the desired mobile services. In this paper, we propose the design of a Cloud-based, Mobile social tv system (CloudMoV). The system effectively utilizes both PaaS (Platform-as-a-Service) and IaaS (Infrastructure-as-a-Service) cloud services to offer the living-room experience of video watching to a group of disparate mobile users who can interact socially while sharing the video. To guarantee good streaming quality as experienced by the mobile users with time varying wireless connectivity, we employ a surrogate for each user in the IaaS cloud for video downloading and social exchanges on behalf of the user. Given the battery life as a key performance bottleneck, we advocate the use of burst transmission from the surrogates to the mobile users, and carefully decide the burst size which can lead to high energy efficiency and streaming quality. Social interactions among the users, in terms of spontaneous textual exchanges, are effectively achieved by efficient designs of data storage with Bitable. These various designs for flexible transcending capabilities, battery efficiency of mobile devices and spontaneous social interactivity together provide an ideal platform for Mobile social tv services. We have implemented CloudMoV on Amazon EC2 and Google App Engine and verified its superior performance based on real world experiments.

Title : Mining Conceptual Relations from Textual Web Content Using Leximancer

Abstract: Concept mining is a process that focuses on extracting ideas and concepts found in documents. The approach is somewhat similar to text mining, with the main difference being that mining a text focuses on the extraction of information rather than ideas. In this paper, we propose concept-based text representation, with an accent on using the proposed representation in different applications such as information retrieval, text summarization, and question answering. This work presents a new prototype for concept mining by extracting the concept-based information from a raw text using leximancer. At the text representation level, we introduce a sentence based conceptual ontological representation that builds concept-based representations for the whole document. A new concept-based similarity measure is proposed to measure the similarity of texts based on their meaning. The proposed approach is domain independent and it could be applied to general domain applications. The proposed approach is going to apply to the domain of information retrieval, and give an assertion for proceeding in the right directions of this research.

Abstract: Internet has become an inevitable part of our lives. While internet offers a mass of useful services which makes communication easier and faster than ever, it presents some threats too along the way. Over the last few years, botnet has risen to become the primary source for various internet attacks such as DDos attacks, spamming, phishing etc. Accordingly, a great deal of research has focused on methods to detect and extenuate the effects of botnets. In this paper, we have analyzed the feasibility of outgoing and incoming traffic i.e. intrusions and extrusions, to detect P2P based botnets. We present an approach that uses a network perimeter mentoring system called bothunter. As a part of the research work, a botnet detection system for peer to peer botnets called P2P-BDS has been proposed.

Abstract: Q-SPIM is an organized advance and incessant progress to enhance software organization's ability throughput quality software that balances time and cost [2]. Such a model developed is verified and validated by the researcher in the course of this research. To improve the overall throughput this approach proves to be a good software up gradation model. This paper work concentrates on upgrading the process as well as organization through Quadrant based approach. This model depends upon the experience on research of software companies and plots the same in different quadrants. The ultimate aim is to develop of a model which would be useful in practice for software development companies to develop quality product. The principle of models for improvement and software process improvement model is described in this paper. The purposed model is a generic model which is beneficial for small firm as well as large firm.

Title : Detection of Clone Attack in Wsn

Abstract: One of the most vexing problems in wireless sensor network security is the node Clone attack. In this attack, an adversary breaks into a sensor node, reprograms it, and inserts several copies of the node back into the sensor network. Cloning gives the adversary an easy way to build an army of malicious nodes that can cripple the sensor network. A few distributed solutions to address this fundamental problem have been recently proposed. However, these solutions are not satisfactory. Therefore first, the desirable properties of a distributed mechanism for the detection of node Clone attacks have been analyzed. Second, the known solutions for this problem do not completely meet our requirements. Third, a new self healing, Randomized, Efficient, and Distributed (RED) protocol for the detection of node Clone attacks has been proposed, and it satisfies the intended requirements.

Index Terms: clone attack, RED, witness distribution, oblivious, performance, WSN.
