The development of high resolution digital cameras for recording of still images and video streams has had a momentous influence on how communication and entertainment have developed during the recent years. Processing of human faces discovers many applications in various domains like law enforcement, security surveillance etc. A standard face processing system consists of face detection, face recognition, face tracking and face rendering. Face detection is one of the most premeditated areas of computer vision in image processing not only because of its thought-provoking nature but because of its broad continuum of applications which requires face detection as the first step. The formative Viola-Jones face detection algorithm is discussed in detail and what is the future prospectus of the face detection techniques. The focus is on the benefits and the drawbacks of the Viola-Jones and why it is the most prominent face detection algorithm and how it can be further improvised in order to meet the needs of today's time. To overcome the cons serial implementation of the Viola-Jones algorithm, the algorithm will be implemented on a parallel platform. The primary objective is to increase the computational speed of the algorithm which may be achieved through parallel implementation using CUDA and OpenCV on GPU (Graphics Processing Unit) and then give comparative analysis of the better computational results between the serial and parallel implementations. © 2016 IEEE.

An effective method for highlight generation from basketball sports videos is proposed in this paper. Video shot classification is done which classify video into three categories that is close-up view, far view and replay. For close-up and far view detection we have proposed the feature based on the percentage of edge pixels to classify the frame into Far or close-up view. A pair of logos determines a replay segment and hence we have proposed an algorithm that determine logo and identify replay segments. Framework for ball detection is also described which is based on calculating intensity difference of two consecutive frames and performing morphology operations. © 2016 IEEE.

The main objective of any power utility is the reliability which is sometimes affected due to failure of outdoor insulators. The insulators of transmission line passing through the coastal area are subjected to marine pollution which contains Sodium chloride (NaCl). In presence of fog or rain, this pollution known as contaminant may lead to flashover of insulator. In this paper an approach to predict the flashover is reported. Experimental set-up was prepared to energise 11 kV composite insulators under AC supply, to create artificial humidity and to measure leakage current under different conditions. Harmonics components of leakage current are analysed by using Fast Fourier Transform (FFT). It was found that when severe arc occurred on the surface of insulator, low frequency components are going to increase especially 3rd and 5th harmonics. The final analysis revealed that the development of flashover due to contamination could be predicted from the analysis of the ratio of 3rd to 5th harmonics of Leakage current signal. © 2013 IEEE.

In this paper, the net irrigation water requirement estimation is carried out for different crops in Limbasi branch canal command area of Mahi Right Bank Canal (MRBC) project located in Gujarat, India. The Hargreaves – Samani approach for reference crop evapotranspiration (ETo) estimation is used for thirteen years of available data and the mean monthly ETo values were computed which were analyzed statistically. The potential crop evapotranspiration (ETc) and net irrigation requirement (NIR) of different crops in kharif, rabi and summer season were estimated. Results show that the NIR values (mm) for kharif crop paddy was 166.8; rabi crops jowar, tobacco & wheat were 404.3, 504.2 & 564.7 and summer crops paddy & bajri were 851.1 & 619mm respectively. © 2015 Association of Agrometeorologists.

Distribution system operators are often challenged by voltage regulation problems, energy losses, and network capacity problems. This paper analyses a real-life 3.9-MVA distribution network in Gujarat State, India. Distributed generation from renewable energy sources like wind and solar, at optimal locations on distribution feeders, may enable energy loss reduction and voltage profile improvement. A methodology is developed and presented for deciding the appropriate location of these embedded renewable generators. Simulations are performed to calculate different scenarios, and the final analysis reveals that the low voltage problem has totally been eliminated on all of the nodes of the distribution network. Complimentary, significant energy loss reductions are also achieved in the distribution, and the network reserve capacity has also increased. © 1969-2012 IEEE.

Conventional Transmission and Distribution systems do not envisage at present any generation on consumer side. However, with the enactment of Indian Electricity Act 2003 and due to the major changes in the Power Sector and the fast move towards liberalization of the energy markets, utilities are inclined to install small capacity generating units to distribution systems. Integration of small capacity generators at load points in the existing electrical network will have impact on voltage regulation, losses, reserve capacity of network etc. In this paper, Renewable Distributed Generators (RDGs) are introduced at a suitable location of a heavily loaded distribution network to minimize distribution losses. Case study has been performed on a real 3.4 MVA distribution system of a particular area of Gujarat state. A methodology has been developed for citing the RDGs at a suitable location in the Network. © 2011 Praise Worthy Prize S.r.l. - All rights reserved.

A movie gathers different fractions like comedy scenes, action, dialogs and songs. Extraction of songs from movies is carried out in this paper with the help of special audio features which helps to distinguish between song and non-song. The algorithm used here performs the operations of movie segmentation, intensity based classification and audio clues based improvements. Intensity based classifications leads to the promising song sequences which may include non-song portions. Such false detections are eliminated using audio clues namely tempo and zero crossing rate. Movies of different genre like comedy, drama, action, thriller, romantic and suspense having different languages specifically Hindi, Marathi, Gujarati and English are taken here for measuring accuracy of this work. © 2015 IEEE.

The main focus of this paper is to study performance of two linear channel estimators, the Least Square Error(LS) and Linear Minimum Mean Square Error(LMMSE) for 2×2 and 4×4 VBLAST MIMO OFDM system with different modulation, BPSK, QPSK, 8QAM and 16QAM as well as with MMSE equalizer at receiver. Channel state information is useful at receiver to remove effect of channel in received signal for efficient recovery of data and at transmitter it is useful to vary modulation order and power allocation according to channel for efficient wireless system. For performance analysis, LMMSE is used instead of Minimum Mean Square Error (MMSE) because of its simplicity as well as it retain MMSE criteria but the constrain is linear. © 2016 IEEE.

Wireless shared medium, randomly moving nodes and multi-hop architecture make mobile ad hoc networks vulnerable to various network layer threats. Grayhole attack is such a prominent network layer threat, in which a malevolent node attempts to establish a bogus route passing through itself and performs packet forwarding misbehavior by dropping a subset of the received data packets in order to degrade the network performance. In this paper, we address this issue by proposing a heuristic approach, referred to as sequence number based bait detection scheme, which attempts to isolate malevolent nodes during route discovery process. The mechanism is incorporated with ad hoc on-demand distance vector routing protocol. Performance of the proposed scheme is compared with an existing scheme under three grayhole adversary models adopting distinct mode of operations. Simulation results under various network parameters depict that the proposed scheme improves network performance depending upon the mode of operations of the adversaries. © 2015, Springer Science+Business Media New York.
