In different sectors of government offices, the original documents are scanned and transfer from one section of office to other through internet technology. Nowadays, internet technology is widely used by every person. There may be many intruders or attacker to hack or manipulate the data like digital images passing through digital channel. To overcome this problem, there is need of authenticity,...
Region duplication or copy move forgery is a common type of tampering scheme carried out to create a fake image. The Held on blind image forensics depends upon the authenticity of the digital image. As in copy move forgery the duplicated region belongs to the same image, the detection of tampering is complex as it does not leave a visual clue. But the tampering gives rise to glitches at pixel level...
OFDM is the next generation transmission technique for high bit-rate communication systems. OFDM has suffered by peak-to-average power ratio (PAPR), it is one of the major disadvantages of OFDM. In this paper, Convolution code is applied to minimize the peak-to-average power ratio (PAPR) and BER of Orthogonal Frequency Division Multiplexing (OFDM) system, and had investigated effect of convolution...
Sanskrit divine sound OM does not have a translation. Therefore, the Hindus consider it as the very name of the Absolute. In the scriptures of ancient India, the OM is considered as the most powerful of all the mantras. It has been recognized that the mantras have beneficial effects on human beings. The syllable OM is quite familiar to a Hindu. It occurs in every prayer. Invocation to most gods begins...
The credibility of a digital image plays a generous role in blind Image forensics. We focus on detection of a typical kind of forgery, referred to as copy-move forgery, which is commonly practiced in the field of blind image forensics. In this kind of forgery as the forged region belongs to same image, it introduces inconsistency at pixel level in the tampered image. In the proposed work, we exploit...
The significance of blind forensic is to detect a forgery without a support of any digital water marking or signature. A common type of forgery is the copy move forgery. In this kind of forgery a portion from the same image is copied and pasted on the object which is undesirable. Such a forgery is generally carried out to conceal a portion or to enhance the image content. The method proposed in this...
Analysis and technique for harmonic elimination is introduced in this paper. The proposed technique eliminates harmonics component from the periodic waveform and it requires only knowledge of fundamental frequency of the periodic waveform. This technique utilizes multipliers, unit delay, adder and subtractor. Adaptation process exactly matches amplitude and phase of fundamental frequency component...
A new filter strategy for harmonic elimination is introduced in this paper. The proposed approach eliminates all harmonics component from the signal (current or voltage) and it requires only knowledge of fundamental frequency of the signal. The proposed active series filter eliminates undesirable harmonics from periodic signal. This filter utilizes an integrator, amplifier, multipliers and subtraction...
Home automation systems have been developed by many researchers. However, the installation and operational cost of such system is relatively high. In this paper, development of two remote monitoring systems using cell phone with a major focus on cost reduction to allow wider utilization even in undeveloped and developing countries are discussed. The first system has relatively simple features and...
This work describes the development of innovative low cost cell phone based remote control application for induction motor-pump based irrigation in agriculture. Rural areas in many states of India are plagued by frequent power cuts and abnormal voltage conditions. The developed system ensures that water is distributed to field whenever normal conditions exist based on task specified. A novel concept...
This paper describes the development of ultra low cost cell phone based remote control application for induction motor-pump based irrigation in agriculture. Rural areas in many states of India are plagued by frequent power cuts and abnormal voltage conditions. The developed system ensures that water is distributed to field whenever normal conditions exist based on task specified. The task is initially...
