چکیده
Image forgery identification assumes a fundamental part in criminological science, the vast majority of the created strategies are concentrating on coarse grained fabrication restriction. In this paper, we introduce forgery detection method based on artifacts obtained by Color Filter Array (CFA) which are used in most digital cameras. Here we make the assumption that forgery removes the artifact due to de-mosaicking algorithm. Our main focus is on the fine grained forgery localization problem, assuming to have no information about the forged pixel.The proposed method is based on a new feature measuring the presence of demosaicking artifact at local level. We proposed a new feature measuring the presence of de-mosaicking artifact even at the smallest 2 X 2 block level with the help of this method we are able to find fine grained forgery localization.

The antenna radiation characteristic is the important parameter to select the shape of antenna and triangular patch antenna gives the better antenna characteristic as compared to other shape antenna with less geometrical structure. Objective of our work is to enhance the characteristics of triangular patch antenna .In this paper we discussed about some previous applied techniques to improve the...

This paper presents effectiveness of cut off frequency of a low pass filter of communication disturbance observer (CDOB). This compensation technique requires system model only and not time model. So we can apply this compensation technique to both constant and variable time delay. In this paper, the validity of compensation technique with simulated result has been shown.

A Parallel multiplier using approximate compressors are proposed in this paper. The two new approximate 4-2 compressors are proposes that the simplified compressors have better power consumption than the optimized 4-2 compressor existing designs. These approximate compressors are then used in the restoration module of a Parallel multiplier. Four different schemes for utilizing the proposed appr...

several edge recognition strategies have now been planned within the past decades. Many are derived from differential strategies such as for example Sobel, Roberts, Laplacian operators, and therefore on. Nevertheless these calculations are quite sensitive to sound, in order to restrain sound before sensing edges. In this report intensive literature review has been presented in numerous edge rec...

4-methylaniline in chlorobenzene reacted with sulphuric acid, sodium thiocyanate and sulfuryl chloride to give 2-amino-6-methyl benzothiazole. This 2-amino-6methyl benzothiazole was later further reacted with 2-(2,2difluoroethoxy)-6-(trifluoromethyl)benzene-1-sulfonyl chloride in the presence of Dichloromethane and anhydrous Pyridine to afford 2-(2,2-difluoroethoxy)-N-(6methylbenzo[d]thiazole-2...
