Abstract

The aim of an object tracker is to generate the trajectory of an object over timeby locating its position in every frame of the video. In this research, we present anobject contour tracking approach using Generalized Gradient Vector Flow(GGVF). GGVF active contour, or snake, is a dynamic curve that moves within animage domain to capture desired image features. Mostly, GGVF is not sensitive toinitial conditions and converges to the optimal contour. Given an initial contournear the object in the first video frame, GGVF can iteratively converge to anoptimal object boundary. In each video frame thereafter, the resulting contour inthe previous video frame is taken as initialization so the algorithm consists of twosteps. In the first step, the initial contour is applied to the desired object in firstvideo frame. The resulting contour is taken as initialization of the second step,which applies GGVF to current video frame. To evaluate the tracking performance,we applied the algorithm to several real world video sequences. Experimentalresults are provided.

Abstract

1.The rule legitimacy from which the right and duty of spending in the faces of charity, identified Islamic economic thought: that the ownership of things to God, and that human Mstkhalaf them, under the theory of succession this enjoined Bari - most would - rights to the money the rich to the poor people and Manajém outside the specified Zakat funds and disbursed in the eight brands, to contribute to the transfer of money from being a tool for hoarding and speculation to her job that I found for it, being an intermediary for exchanges to achieve mutual interests and benefits among the people

1.إن القاعدة الشرعية التي ينطلق منها حق وواجب الإنفاق في وجوه البر والإحسان ، حددها الفكر الاقتصادي الإسلامي : في أن ملكية الأشياء لله تعالى ، وان الإنسان مستخلف عليها ، وبموجب نظرية الاستخلاف هذه أوجب الباري - جل شأنه- حقوقا في أموال الأغنياء لفقراء الناس ومحتاجيهم خارج أموال الزكاة المحددة والمصروفة في أصنافها الثمانية، للإسهام في نقل النقود من كونها أداة للاكتناز والمضاربات إلى وظيفتها التي وجدت من أجلها ، كونها وسيطاً للمبادلات لتحقيق المصالح والمنافع بين الناس .
