Human face is an important object in an image database due to its unique features (eyes, mouth, nose etc.) in every human being. The detection & recognition of a face in an image using template matching is one of the profound research interest in the field of image processing. Various approaches have been proposed in the literature to extract the visual facial features based on texture, color,...
Virtual Reality is based on the notion of immersion i.e. a new technological advancement in the field of human-machine interaction bringing it closer to real life. It is a technology for simulation of a real or virtual world in which one can immerse, touch, & sense the objects with the virtual presence in that 3-D world. This paper reviews the ideas & concepts behind the architectural representation,...
Near zero refractive index based materials have been useful for building antennas with high directivity at the broad side direction. We demonstrate a directive multi slot antenna structure with a near zero refractive index substrate that is capable of directing the main lobe of the radiation pattern away from the broad side. The tilt of the main lobe is a function of the position of the source excitation,...
The power, speed, area and energy constraints are the major user concerns, when it comes to choosing the appropriate logic family for new applications. This paper introduces customizable logic families and presents a comparative analysis of such logic families, to enable the user to make a robust choice. Energy efficiency has been identified as one of the most required features for modern electronic...
Big data has created an era of tera where bulk volume of data is being collected at escalating rates. Due to increase in storage capacities, processing power and availability of data, the size of global data is growing in zeta-bytes. Hadoop is one of the technologies in the big data landscape for analyzing the data through Hadoop Distributed File System and Map-Reduce. Job scheduling is an important...
The major drawback of multicarrier transmission such as Orthogonal Frequency Division Multiplexing (OFDM) and Wavelet Packet Modulation (WPM) is their high Peak-to-Average Power Ratio (PAPR). In this paper, we propose Genetic Algorithm (GA) based approach for the reduction of PAPR. The GA approach has proved to be an efficient optimization tool for the reduction of PAPR as well as the computational...
