China is a vast and overpopulated country in the eastern Asia whose energy security and supply is the most important factor of economic growth and consequently, economic, social and political security. By the past decades, its leaders have understood the key role of economic growth and development in the economic and political security of china. Thus, they have put all their concentration on th...

We present a novel method for the incorporation of shape information into active contour models, and apply it to the extraction of line networks (e.g. road, water) from satellite imagery. The method is based on a new class of contour energies. These energies are quadratic on the space of one-chains in the image, as opposed to classical energies, which are linear. They can be expressed as double...

in this paper, we propose a novel method for fully automatic detection and tracking of human heads and faces in video sequences. the proposed algorithm consists of two modules: a face detection module and a face tracking module. the detection module, detects the face region and approximates it with an ellipse at the first frame using a modified version of adaboost cascaded classifier. the detec...

In recent years, increasing attention has been paid to the blue economy and its economic environmental benefits. Renewable energies are an alternative fossil fuels can contribute reducing carbon footprint of maritime sectors general economy. This article aims analyze scientific production in Web Science (WoS) database propose some measures for future actions. The results indicate new trends art...
