India is a multilingual multi-script country. In every state of India there are two languages one is state local language and the other is English. For example in Andhra Pradesh, a state in India, the document may contain text words in English and Telugu script. For Optical Character Recognition (OCR) of such a bilingual document, it is necessary to identify the script before feeding the text w...

A novel optical edge-projection method is proposed for surface contouring of an object with low reflectivity. A structured light edge is projected onto a dark surface, and the image is captured by a CCD camera. The object contour is evaluated with an active triangular projection algorithm, and one obtains a whole-field three-dimensional contour of the object by scanning the optical edge over th...

ABSTRAC: -This research aims at the extraction of geometric features from Urdu ligatures. Though structural features are robust, its extraction and analysis is exceptionally complex and time-consuming task. The extraction and analysis is uncomplicated in case of the geometric features. Geometric features are language, script and font independent. There are twelve significant geometric features ...

Mobile Ad-hoc Networks (MANETs) by contrast of other networks have more vulnerability because of having nature properties such as dynamic topology and no infrastructure. Therefore, a considerable challenge for these networks, is a method expansion that to be able to specify anomalies with high accuracy at network dynamic topology alternation. In this paper, two methods proposed for dynamic anom...

This paper proposes algorithms to localize vehicle number plates from natural background images, to segment the characters from the localized number plates and to recognize the segmented characters. The reported system is tested on a dataset of 560 sample images captured with different background under various illuminations. The performance accuracy of the proposed system has been calculated at...

We study generalization properties of linear learning algorithms and develop a data dependent approach that is used to derive generalization bounds that depend on the margin distribution. Our method makes use of random projection techniques to allow the use of existing VC dimension bounds in the effective, lower, dimension of the data. Comparisons with existing generalization bound show that ou...

In this paper, we present a new color structured lighting for 3D profile measurement by projecting a pattern of color stripes. The advantage of using color pattern is that it simplifies the difficult matching problem of using a multiple-line stripe pattern. The problem of finding the correct color stripe correspondence between light source and images is solved by accurately calibrating the syst...
