Many governments have delivered their services in ways that meet the desires of the citizens and businesses they serve, enabling them to interact securely in places and at times that are convenient for them. E-government is one of the most important achievements of the Internet. Successfully implementing e-government requires a level of trust on the part of all transaction parties. There are several...
Linear motion and out-of-focus blur often coexist in a surveillance system, which degrade the quality of acquired images and thus complicate the task of object recognition and event detection. In this work, we present a point spread function-based (PSF-based) approach considering fundamental characteristics of linear motion and out-of-focus blur based on geometric optics to restore coexisting motion...
This paper describes how we can use existing mobile technology to track the vehicle. Here the embedded system along with the mobile is used to prevent the vehicle from being stolen and also if the vehicle is stolen then its location can be tracked. Mobile technology is the fastest growing communication mode. In todaypsilas mobile technology we all are acquainted with short message service (SMS). In...
In this article, we propose a general-purpose disaster support system based on generalized (multiplicatively-weighted order-k Minkowski-metric) Voronoi diagrams. The proposed system is capable of handling disasters (or emergency units) having different weights in the complete order from 1 to k in the three popular Minkowski metrics (Euclidean, Manhattan and Maximum distance space). The proposed model...
Based on spatial and DCT domains this paper proposes a novel digital watermark solution for the color image of screen stream in multimedia courseware. It embeds visible watermark into spatial domain adaptively, and also embeds invisible watermark encrypted by chaotic sequence into the remained area of the screen color image to achieve protected screencolor image with dual digital watermark embedded...
