 Abstract

This paper focuses on the digital image authentication and forgery localization using demosaicing artifacts. The aim is to make an algorithm allowing a bridge between the color filter array pattern and demosaicing algorithm estimation, and thus the statistical analysis of demosaicing artifacts in spatial domain to reinforce the authentication and localization performance. After analysing the evolution of demosaicing traces privately acquisition pipeline, a robust feature statistic characterizing demosaiced digital images is first developed on the thought of the noise residue of green channel. Such a feature statistic may be a smaller amount sensitive to the edges problem because only the graceful region of green channel is used within the event. Next, one normal mixture model is proposed to elucidate the probability distribution of feature statistics for both original and tampered images. Therefore, normality tests are often used to authenticate automatically digital images. The authentication performance are often further improved by human interpretation of supported graphic tools. Finally, a penalized expectation-maximization algorithm is used to localize forged areas in tampered images. Numerous comparative studies on four well-known datasets show that the developed algorithm yields better performance and robustness than existing forensics algorithms of the same kind

In today�s world the expansion of medical field is tremendous. Early diagnosis and appropriate treatment planning of different diseases requires the precise information which can be obtained through the image fusion of various modalities of medical images. Images fusion is the process of combining the relevant information from a set of images into a single image, where the resultant fused image will be more informative and complete than any of the input images[1]. Here we are combining images of CT scan and MRI scan of the brain, DWT (Discrete wavelet transform) based image fusion is implemented. Then segmentation process is employed to extract the abnormal areas or affected regions from the fused images and Convolutional Neural Network is used to detect the normal and abnormal brain image. And also an AES encryption technique is employed to convert the report of the fused image to cipher text

Nowadays the endoscopic images captured through video capsule endoscopy is less accurate and high noise. So it is difficult for a doctor for better diagnosis. The captured endoscopic images are less secure so it is easy for unauthorized users to misuse the data. So there is a need for encryption of image. The main challenge in video capsule endoscopic system is its security. In this paper, a data compressor for video endoscopy application is presented. The algorithm consists of Golomb Rice coding. Produces output which have compression ratio of 80% and very high peak signal-to-noise ratio (over 36dB).

 Abstract

Traffic accidents are one of the major issues in today�s world. The accident occurs due to our mistakes and also neighboring vehicle�s mistake. Many systems are developing to avoid this. But the accidents are increasing. In this paper, a system is developed that continuously detects the number plate of neighboring vehicles and sent that through telegram. And also the eye of the driver is monitored continuously to detect the fatigue of driver. If the eye is closed a buzzer alert is produced. The number plate recognition helps the investigators to find the neighboring vehicles if any accident occurs.OCR is used for number plate character extraction. The alert is produced using text to speech alarm.

 Abstract

Nowadays finding parking spaces is a difficult one. The common method of finding a parking space is manual where the driver usually finds a space on the street through luck and experience [1]. In the case of private parking areas, when we want to park our vehicles they provide the parking space if any vacant parking spot is available. Using this system the drivers can easily identify the nearest public parking spot and vacant private parking spot. The drivers can also reserve the vacant private parking spot.

 Abstract

his paper describes the classification of a subset of printed or digitized Gujarati characters. Gujarati belongs to the genre of Devanagari scripts from the Indian subcontinent. Very little work is found in the literature for recognition of Indian language scripts. For this paper a subset of similar appearing Gujarati characters was chosen and subjected to classification by different classifiers. The sample and test images for the characters were obtained from digital images available on the Internet and from scanned images of printed Gujarati text. For their classification, the Euclidean Minimum Distance and the k�Nearest Neighbor classifiers were used with regular and invariant moments. The characters were also classified in the binary feature space using Hamming Distance classifier. The pa- per presents the recognition rates for these classifiers. A recognition rate is achieved. The work described in this paper is preliminary; however, since ICDAR�99 is being held in India, we hope that this would be of interest to the participants.

 Abstract

This study dealt with the study of different types of high school management such as Government school, Private School, Adhoc-aided School and Deficit School of Aizawl City in terms of their students� home adjustment, health adjustment, social adjustment and emotional adjustment. The researcher adopted descriptive research method where Bell�s Adjustment Inventory (BAI- o) developed by Dr. R.K.Ojha (2011) published by National Psychological Corporation, 4/230, Kacheri Ghat, Agra was used as a tool for this study. The population included all class IX students in the high school of Aizawl and the sample consisted of one(1) high school each from Deficit and Ad-Hoc, two(2) High School from Government and five(5) High School from Private management. The selection was done by using stratified random sampling process. The findings revealed that n the area of �Home�, �Health� and �Social� adjustment, Private schools showed the best adjustment. However, the emotional adjustments of different school management systems are very poor and they all fall in the category of �very unsatisfactory�. Discussions were also presented in the light of the findings.

ABSTRACT: Concrete is strong in compression but weak in tension and brittle also. Cracks also start forming as soon as the concrete is placed. These 3 drawbacks don�t permit the use normal concrete in pavements as they lead to lack of ductility along with fracture and failure. These weaknesses in concrete can be mitigated by using fibers as reinforcement in the concrete mix. Waste materials in the form of polyethylene and tires cause environmental pollution which leads to various health problems. Polyethylene and waste tires can be recycled and used effectively in the concrete as reinforcement in the fiber form. Polyethylene is a synthetic hydrocarbon polymer which can improve the ductility, strength, shrinkage characteristics etc. This research deals with the effects of addition of polyethylene fiber on the properties of concrete. Polyethylene and tire fibers were cut into the size of 30mm x 6mm and they were used 1.5% each by volume. Grade of concrete used were M30, M35 and M40. IRC 44:2008 was followed for the design of concrete mix. In this study, the results of the Strength properties of Polyethylene fiber reinforced concrete have been presented. 4 point bending test and double shear test were performed in the laboratory for flexure and shear strength determinations. There was seen an increase of 18% in the 28 day compressive strength along with an increase of 39% in flexure and 32% in shear strength. 22% decrease in 4 point bending test and 36% decrease in double shear test in deflection was found out from the experiments. Theoretical analysis of deflection was carried out by the help of energy methods. Practical values were verified with the theoretical values within the permissible limits. Finally it can be concluded that polyethylene and tire can be used effectively in reinforced cement concrete.

 Abstract

This article aims to give the current scenario of Indian commercial banks. It plays a essential part in the national development. In our economy there are lot of ups and downs in recent times. The banking system forms origin of the money management of any economy. The assimilation of 14 big banks in 1969 and another 6 banks in 1980 and implementation of reforms, appear a change in class and mass banking, traditional banking to e-banking to more profitable, efficient and sound banking system. However, especially the defenseless groups, like as lower category and lower groups of income, carry forward and to go on expected from even the most important services and also some opportunities provided by the financial sector. To issue of such financial exclusion in a holistic manner, it is essential to know about the services given by banks is available to every individual. A important part is being carry on by monetary policy for full betterment across the global to renew monetarily eliminate community and that is counted as 2.5 billion, of which, one third is populated in India. Financial inclusion is taken from the initiatives of United Nations, which extensively reported the important goals of the policy as access to deep limits of economic services to all at an affordable cost, which started its operation efficiently in India in the year 2015.
