Image processing is a method of analyzing and manipulating the digitized image to reduce noise and to improve its quality. It usually refers to digital image processing, but image processing can also be done for optical and analog types. The input is an image which can be either a photograph or video frame while the output can either be an image or a set of characteristics of an image.The analysis of an image requires techniques that can identify colors, shades etc. we present a method that focuses totally upon tampering detection and to provide authentication when a video is transmitted from one user to another. It also concentrates on reducing noise distortion. This is made possible by means of using modified QDCT and by embedding watermark signals. Â© Copyright 2015 ACM.

This paper presents the study of Multi Document Summarization (MDS) of medical documents with the help of clustering model and building dictionaries. This paper also tells about efficiency of the method in practical abstract. This paper aims to reduce the complexity of the process by using the sequence of different methods. A summary generated from this method is evaluated against human written summaries. The objective of the multi document summarization is to generate an efficient summary with the help of sequencing a series of methods and algorithms. It also takes the keyword from the document and makes a local dictionary which is helpful in extracting summary from the document.It generates dramatically better summaries than an extractive summaries based on sentence extraction, reordering components and omitting useless words or lines. This presents an inter clustering method that takes events, topics or points from multiple clusters as inputs and then selects the most salient and relevant points to make the output. This also provides users a control over the summarization process using different methods. Besides the general idea and concept, we discuss the benefits and limitations concerning these methods. With the aim of enhancing MDS with this approach we can generate a better summary. © Research India Publications.

Multi - Document summarization using cluster model incorporating building dictionary method

Preserving the privacy of the vehicle on the move is an important challenge in VANET's. Vehicles can be loaded with Pseudonyms that can be changed frequently in specific intervals to prevent tracking of the vehicle by a third party. Yet, this scheme supports only a short travel from home and moreover the RSUs' do not play a major role. Therefore, this paper proposes a scheme of implementing a security mechanism using Blind Signature, where the Road Side Units in collaboration with the Trusted Authority generates the keys to be transmitted to the vehicles. These short lived keys are used to send and receive messages on the roads. The paper considers two ideal places where the vehicle stops for some long time, one being the traffic signal and the other is a parking lot. The key update time for the two scenarios using Blind signature is compared with the earlier scheme where the vehicle changes its Pseudonym based on the neighbouring vehicle. The proposed approach has been evaluated using simulations in Ns-2.

Need for high speed internet connectivity has led to a substantial research in switching systems. Buffered crossbar switches have received a lot of attention from both research and industrial communities due to their flexibility and scalability. Designing a scheduling algorithm for buffered crossbar switches without starvation is a major challenge as of now. In this paper, we propose a Delay based Prioritized Queue with Round-robin Scheduler (D-PQRS) which uses no speedup. Simulation result shows that DPQRS reduces the starvation considerably with maximum throughput and minimum delay comparable to PQRS and LQF-RR.

The current work was designed to isolate and characterize chitin degrading bacteria. Among the 55 bacterial colonies isolated from 7 different soil samples, 4 isolates were capable of degrading chitinase, among which one strain VITSD3 was found to be potent. Based on the morphological, biochemical and molecular characterization of VITSD3 the isolate was confirmed as Bacillus cereus (Genbank accession number: KC961638), designated as Bacillus cereus VITSD3. The crude enzyme had a total activity of 220 U, precipitated with 44.8 U and 22.5 U for dialysed sample. The hydrolysed product NAG (N-Acetyl Glucosamine) from chitin was analysed by high-pressure liquid chromatography (HPLC).The molecular weight of the chitinase was determined using SDS PAGE and found to be 55 kDa. The partially purified chitinase produced from Bacillus cereus VITSD3 showed antifungal activity against Aspergillus fumigatus (18 mm), Aspergillus niger (6 mm) and Aspergillus flavus (15 mm). Hence the investigation suggests a potential benefit of partially purified chitinase extracted from Bacillus cereus VITSD3 which will serve as an excellent antifungal potential with therapeutic use. © 2015 Universidade Federal de Uberlandia.

Body health monitoring is very important to us to make sure our health is in excellent condition. One of the vital parameter for this device under consideration is the heart rate (HR) data apart from other significant body monitoring parameters such as temperature, weight and blood pressure which are also significant to body health monitoring. In this project we describe the design of low cost heart rate monitoring device from fingertips based on the Bluetooth technology. The entire system is comprised of several parts such as Heart Rate module, Android application and Bluetooth module. The Heart Rate (HR) module picks up heart rate signal by a non-invasive technique (Photoplethysmography) from the subject (patients) and sends it (signal) wirelessly to computer or android application using Bluetooth module. This system can be embraced and combined as a part of telemedicine constituent. The data received from heart rate module can be saved and viewed for further medical usage. The result from this device prototype can be utilized for various clinical investigations, indeed these Bluetooth‟s signal can be transmitted between 15 to 20 meters radius. © Research India Publications.

A secure robust on-demand multicast routing protocol over mobile Ad Hoc networks

Currently, a huge amount of data is available across various domains including biological data. Classification of these data, clustering, and data analysis is tedious and has become popular in recent research. In particular, bio-inspired computing is the field that mends together mathematics, computer science, and biology to develop tools to store, scrutinize, and interpret the biological data. It is also used to solve real life problems like sequencing biological data, data clustering, and optimization. Swarm intelligence is an emerging field of biologically inspired artificial intelligence technique that is based on the behavioral models of social insects. This chapter provides an overview of swarm intelligence algorithms in solving bio-inspired computing problems. It is an attempt to explore the working nature, applications, and generative power of various bio-inspired computing algorithms. The main intent is to furnish a comprehensive study of swarm intelligence algorithms in the literature so as to inspire further research in the area of biologically inspired computing.

Mobile ad hoc networks (MANETs) consist of a collection of wireless mobile nodes which dynamically exchange data without the need of fixed infrastructure or a wired backbone network. On-demand routing protocols use a flood-based discovery mechanism to find routes when required. Since each route discovery incurs high overhead and latency, the frequency of route discoveries must be kept low for on-demand protocols to be effective. On-demand routing protocols can achieve better performance and scalability by computing multiple routes in a single route discovery. Multipath routing is one of the applied approaches in mobile ad hoc networks to address their limited bandwidth and high route breakage rate. This paper proposed a novel approach called multipath on-demand routing (MPODRT), which reduces the routing overhead by using secondary paths by computing fail-safe multiple routes. © Research India Publications.
