Problem statement: Image sensors and communication channels often introduce impulse noise in image transmission. The most common filters available to remove such noise are median filter and its variants but the major drawbacks identified with them are blurring of edge detail and low noise suppression. To preserve the sharp and useful information in the(More)
In this article, we first review some aspects of functional magnetic resonance imaging (fMRI) paradigm designing for major cognitive functions by using stimulus delivery systems like Cogent, E-Prime, Presentation, etc., along with their technical aspects. We also review the stimulus presentation possibilities (block, event-related) for visual or auditory(More)
— In the Transmission of Videos over channel, Video frames are corrupted by salt and pepper noise (Impulse Noise), due to faulty communication systems. The objective of this paper is to implement a better filtering technique that makes the noisy video frames to noise free video frames. Median filters are the best known non-linear digital filters based on(More)
In recent years, there is a rapid growth with amount of data collections in hardware, software and networking, data source sharing, transaction oriented data etc., This type of stream data also contains private and sensitive information. A new topic in the area of privacy preserving data mining in stream data is quite challenging, in which data grows(More)
Software Designs must be evaluated in Software Development Process so as to avoid bugs and unsatisfactory performances. Concerning performance and real-time properties modeling, OMG specified the UML Profile for Schedulability, Performance and Time Specification (SPT). UML is the standard OO modeling Language our system, but UML is too static to model the(More)
The increasing nature of World Wide Web has imposed great challenges for researchers in improving the search efficiency over the internet. Now days web document clustering has become an important research topic to provide most relevant documents in huge volumes of results returned in response to a simple query. In this paper, first we proposed a novel(More)
Coronary heart disease (CHD) is caused by a narrowing of the coronary arteries that supply blood to the heart, and often results in a heart attack. Each year about millions mankind suffers from heart attack. About maximum of those heart attacks are fatal. ECG signal is very important signal in the cardiology. Different artifacts are the reason behind the(More)
