Abstract: PURPOSE: A composition method for service-oriented overlay multicast tree is provided to reduce overhead which is needed to calculating delays between existing node and the new node. CONSTITUTION: A joining request message is received from a new node in order to join a multicast group(S310). An available joining time point for the joining request is checked(S320). If there is an available joining time point, whether the node is leaf node or not is determined(S330). If the node is a leaf node, a joining response message is transmitted to the new node(S340). The new node receiving the joining response message requests a connection(S350).

Abstract: According to an embodiment of the present invention, a method for receiving contents in a node of an overlay network is provided. A method for receiving contents receives contents from a node which transmitted a response for a contents inquiry message by flooding the contents inquiry message to an overlay network according to the minimum spanning tree when the node which received contents identification information from a user equipment does not have the contents. [Reference numerals] (201) Smart node 1;(202) Smart node n_1;(203) Smart node n_2;(AA) User equipment;(BB,EE,GG) Yes;(CC,DD,FF) No;(S200) Contents identification information;(S201,S205) Possessing the current contents?;(S202,S209) Serving smart node;(S203,S211) Providing contents;(S204) Flooding the contents inquiry message;(S206) Ignoring the contents inquiry message;(S207) Contents response message;(S208) Requesting contents transmission;(S210) Transmitting the contents

Abstract: A high speed region merger method of a watershed extracting exact object information and an apparatus thereof are provided to merge region at high speed without repetitive merge. An average brightness value of pixel values is evaluated in local regions(100) divided into local watershed. The difference of the average intensity with the domain frame is calculated. One and six are determined as a decision region in a background region. Four and eight are determined as the decision region in an object region. The difference of the average intensity of the domain frame is inputted to a hierarchical queue(102) in the numerical order of localized regions. An altitude(103) of the hierarchical queue is determined based on the difference of the average intensity by the value inputted to the hierarchical queue.
