Mobile Ad-Hoc Network (MANET) is an emerging area with practical applications. An Ad-Hoc network consists of a collection of wireless mobile nodes that are capable of communicating with each other without the use of a network infrastructure. However, routing security in MANETs appears to be a problem due to open medium, dynamic topology and constrained(More)
Video tracking is the process of locating a moving object in time that is visualized by camera and are widely used in surveillance, animation and robotics Tracking describes the process of recording movement and translating that movement onto a digital model. The set of constraints that produce the most accurate tracking is the one that describes better the(More)
A two and half year old male child was seen with systemic hypertension, left ventricular dysfunction, mitral regurgitation and congestive cardiac failure. Examination revealed adenoid hypertrophy. He was also suffering from obstructive sleep apnea. He was being treated with anti-hypertensive and anti-failure drugs. Adenoidectomy was performed following(More)
Synthetic Aperture Radar (SAR) techniques represent a promising alternative compared to traditional surveillance methods. The capabilities of satellite based SAR systems are confirmed and specific data exploitation methods are still to be developed to provide an efficient automatic interpretation of SAR data. The mean of this paper is to analyze and compare(More)
Segmentation of target is an important step in forming realistic target models. To assist in classifying the relevant literature, two types of segmentation are identified where each type adds its own additional level of uniqueness. The first type is composed of the simplest forms of image analysis through thresholding, the second is characterized by region(More)
The problem of texture Segmentation involves subdividing an image into differently textured regions. Gabor filters produce outputs which are notably distinct for the different textured regions. Detecting the discontinuity in the filters output and their statistical properties help in segmenting and classifying a given image with different texture regions.(More)
Feature selection problem often occurs in pattern recognition and more specifically in classification. Features extracted from feature extraction methods could contain a large number of feature set. In original feature set, some of them can prove to be irrelevant, redundant and even unfavorable to classification accuracy. So it is essential to remove these(More)
An exceptional effort has been extended in making a computer recognize both typed and handwritten characters automatically. Quite recent still today, the characters of English Language is been the main explore area for our researchers. Tamil under Asian languages has little or no attention is been given. The challenges posed by Indian languages are(More)
