Now a day's vehicle recognition has become a wide area of research. Vehicle recognition has several applications such as in automatic parking, toll gate management etc., Because of numerous applications, vehicle recognition in computer vision has become a research area in Intelligent Transport System (ITS). There are many different vehicles from different manufacturers which are increasing day by...
Now day's computer vision techniques are used for analysis of traffic surveillance videos which is gaining more importance. This analysis of videos can be useful for public safety and for traffic management. In recent time, there has been an increased scope for analysis of traffic activity automatically. Computer based surveillance algorithms and systems are used to extract information from the videos...
High dependability on Instrumentation and control (I & C) systems calls utmost importance for smooth functioning as well as the safety of Nuclear power plants. I&C systems are employed for monitoring of the parameters, control of these parameters and protection of the plant and persons. The Embedded systems play major role in design and development of I&C systems. While designing I&C...
Feature selection or variable reduction is a fundamental problem in data mining, refers to the process of identifying the few most important features for application of a learning algorithm. The best subset contains the minimum number of dimensions retaining a suitably high accuracy on classifier in representing the original features. The objective of the proposed approach is to reduce the number...
This paper details the Process Disturbance Analyzer (PDA) for 500 MWe Prototype Fast Breeder Reactor (PFBR). The various parameters that assist safe operation of the reactor are to be monitored continuously to aid post event/disturbance analysis of the plant. Some critical analog and digital signals from circuit breakers, power supply, variable speed drive etc., are fast in nature and are to be scanned...
This paper presents, analysis of magnetizing inrush current for different voltage angles and harmonic analysis of that inrush current using different FFT windowing techniques. Time domain simulations were used to solve the inrush phenomenon. Square, Welch, Hanning and Parzen windows were used to truncate the obtained inrush current harmonic spectrum for investigation and with parzen windowing the...
Digital image watermarking is a technology that it is used to hide the information in an image for copy right protection. The main issues in watermarking are robustness and fidelity. In this paper, Discrete Wavelet Transform (DWT) is applied and Singular Value Decomposition (SVD) is also used. Genetic algorithm is implemented for embedding the watermark to achieve robustness and fidelity. It is an...
Time-series observations were conducted off Visakhapatnam, central west coast of Bay of Bengal, from October 2007 to April 2009 to examine the influence of physical and atmospheric processes on water column nutrients biogeochemistry. The thermal structure displayed inversions of 0.5 to 1.0° C during winter and were weaker in summer. The water column was vertically stratified during the entire study...
Digital watermarking algorithms are prune to different attacks. Of these geometric attacks are recognized as one of the strongest attacks for digital watermarking technology. In this paper, we implemented a BNA(Blind Normalization Algorithm) watermarking algorithm resistant to geometrical distortions (rotation, scaling and aspect ratio)and different other attacks(histogram equalization, JPEG, noise)...
