Crypto-biometric system (CBS) is a combination of biometrie with cryptography to enhance network security. Biometrie is the most trustworthy measure to identify a person uniquely using his or her behavioral and physiological characteristics. Cryptography is an effective concern to the security of information. The security of cryptography depends on the strength of cryptographic key and strength of...
In this paper, low complexity reconfigurable hardware architecture for adaptive median filter is proposed and a comparative study of hardware based median and adaptive median filter is presented. An efficient development of median & adaptive median filter is presented for removal of impulse noise mainly salt & pepper noise from digital Images. Performance measurement of mean square error (MSE)...
Geographical Information Systems (GIS) are special types of information systems managing geo-spatial data. The GIS is used to manage geo-referenced information and it represents spatial position of any location into digital map. The GIS also facilitates the user to retrieve spatial information easily using a lot of geographic functions such as data integration, mapping, and overlaying, buffering,...
Feature selection from microarray data has become an ever evolving area of research. Numerous techniques have widely been applied for extraction of genes which are expressed differentially in microarray data. Some of these comprise of studies related to fold-change approach, classical t-statistics and modified t-statistics. It has been found that the gene lists returned by these methods are dissimilar...
The guard zone computation problem is of utmost importance in the domain of VLSI physical design automation as one of the major purposes is to find an optimized way to place a set of two-dimensional blocks on a chip floor. Beyond this, it has huge significance in the field of robotic motion planning, Geographical information system, automatic monitoring of metal cutting tools and design of any embedded...
Cooperation of the multi-robots is an upcoming appealing area of research in the field of robotics. In this paper, two arduino based mobile robots are carrying a stick by cooperation towards their goal avoiding obstacles. The path planning algorithm is designed with the help of Artificial Bee Colony Optimization (ABCO) algorithm which chooses the optimized path by minimizing the distance between the...
This paper presents the results of an experimental study on the shape and path of small bubbles rising in stagnant water. Bubbles, generated at the bottom of the chamber holding water, rise through it. A high speed camera (1000 fps, Kodak, Model 1000 HRC) together with a 90 mm Macro lens is placed at a height of 60 cm from the bottom of the chamber. It is linked with a PC. The commercial software...
Cell and microparticle analysis is one of the major task in all pathological labs. The concentration profile, such as red blood cell (RBC), white blood cell (WBC), platelet concentration are the key parameters for early diagnosis of many diseases. However in most laboratories, especially in resource limited settings, this diagnosis are done manually using conventional optical microscope. This manual...
Clifford Algebra (CA) and its significance in a color image representation is discussed in this paper. Multivector in 3D space explains the representation of color & grayscale image following RGB color model. The colors are defined by the color blades in multivector. Gray value of a pixel is determined by grayscale vector in multivector form. Rotor operators are applied on different shades of...
Interdigitated Finger Capacitors or Comb Drives have an integral role in MEMS designing. Though numerous applications of this device have been implemented, a lack of uniform linearity still remains. We have thus endeavored to improve the same. The results thus obtained suggested a change of design affects the linearity far more than a change in any other parameter and thus we present a novel change...
In the three-dimensional (3D) construction of brain tumour using several slides of magnetic resonance imaging (MRI) has always been a keen interest for diagnosis and for research purpose. In this paper we propose a new approach for three-dimensional construction and its volume calculation from a series of two dimensional (2D) MRI images. Each of the abnormality detected MRI image are successively...
This paper describes the development of a power measuring device (smart meter) capable of identifying the instantaneous running household loads and measurement of basic electric parameters. This real time basis load identification facility is exploited to estimate the load respective tariff for different Time-of-Use (TOU) of electricity for both the consumer and utility ends. The information regarding...
An image is comprised of focused and non-focused objects and focused objects are treated as decisive objects. Primary task of image registration process is the associated shape analysis of the images under consideration. Shape analysis of the image is the identification of outer and inner border line characteristic of the decisive objects along with other characteristic features of the images. In...
The linear analysis of digital phase locked loop (DPLL) does not include finite precision arising owing to the limited size of register or memory for processing or storing the coefficients or data in most of the literatures. This truncation in word length results a serious degradation in DPLL performance. This paper addresses a problem where a truncation error is purposely introduced at the phase...
A compact suspended planar patch antenna is presented for microwave imaging sensor array designed at ISM Band. The radiating patch of the compact suspended antenna is placed at a height of 5mm considering air dielectric substrate (εr = 1.001). The antenna is fed by a coaxial probe and single shorting post is placed in its lower left corner of radiating edge. More compactness is achieved by cutting...
Electrical Impedance Tomography (EIT) is a nonlinear ill posed inverse problem which is very prone to modeling errors. 2D-EIT reconstructs the spatial distribution of the object impedance profile comparing the measurements of boundary voltage data collected from a 3D object with the calculated data generated from an absolute 2D domain in computer. As the 2D-EIT assumes current conduction in two dimensional...
SnS is a promising material for solar cell absorber layer application due to its low cost, easy availability and less toxicity than other semiconductor material used for the same purpose. SnS thin films as an absorber layer for photovoltaic application are deposited using chemical bath deposition (CBD) having a thickness of 550 nm from a solution containing SnCl2.2H2O, TEA, TA and NH3OH NH3OH is used...
