    • The invention relates to a method of selecting a RTP (Real Time Protocol) element in a dynamic multicast tree for a multimedia conference and a record medium recorded with a program for realizing the method that can be read by computers, and in particular to a method of selecting a RTP element in a dynamic multicast tree for distributing an overload applied to the root node of the dynamic multicast tree and a record medium recorded with a program for realizing the method that can be read by computers. The method comprises the steps of: (a) confirming in the RTP element if the RTP element is subscribed to the dynamic multicast tree that a new multimedia terminal wants to join; (b) if the RTP element is not subscribed to the dynamic multicast that the new multimedia terminal wants to join according to a result of the confirmation in the step (a), joining in the RTP element the root node of the dynamic multicast tree and then causing the new multimedia terminal to join the dynamic multicast tree of a multimedia conference system; and (c) if the RTP element is subscribed to the dynamic multicast that the new multimedia terminal wants to join according to a result of the confirmation in the step (a), causing the new multimedia terminal to join the dynamic multicast tree of the multimedia conference system.
    • 本发明涉及一种选择用于多媒体会议的动态多播树中的RTP(实时协议)元素的方法,以及用用于实现可由计算机读取的方法的程序记录的记录介质,特别涉及一种方法 在动态组播树中选择RTP元素以分配应用于动态组播树的根节点的过载,以及记录有用于实现可由计算机读取的方法的程序的记录介质。 该方法包括以下步骤:(a)在RTP元素中确认RTP元素是否订阅新多媒体终端想要加入的动态多播树; (b)如果RTP单元根据步骤(a)中的确认结果未订阅新多媒体终端想要加入的动态多播,则将RTP元素加入到动态多播树的根节点和 然后使新的多媒体终端加入多媒体会议系统的动态组播树; 以及(c)如果RTP单元根据步骤(a)中的确认结果订阅了新的多媒体终端想要加入的动态多播,则使得新的多媒体终端加入多媒体的动态多播树 会议系统

    • The invention relates to a content-based image retrieval apparatus and method via relevance feedback by using fuzzy integral and a computer readable record medium storing programs for realizing the apparatus and method. According to the invention, it is provided a content-based image retrieval apparatus and method in which image features are associated by using fuzzy integral and parameters necessary for the fuzzy integral are adjusted in similarity calculations via relevance feedback so as to improve search results. The method comprises the steps of: measuring similarities according to feature between images stored in a database and a new query image; associating the similarities measured according to feature by using the fuzzy integral to measure similarities according to the fuzzy integral; bringing images sequentially in the order of higher similarity according to the finally obtained similarities and transmitting a search result; and recalculating similarities according to feature via relevance feedback about the query result to output converted images.
    • 本发明涉及一种基于内容的图像检索装置和方法,其通过使用模糊积分的相关性反馈和存储用于实现该装置和方法的程序的计算机可读记录介质。 根据本发明,提供一种基于内容的图像检索装置和方法,其中通过使用模糊积分图像特征相关联,并且通过相关性反馈在相似性计算中调整模糊积分所需的参数,以便改善搜索结果。 该方法包括以下步骤:根据存储在数据库中的图像和新的查询图像之间的特征来测量相似度; 通过使用模糊积分相关联的特征测量相似性,根据模糊积分测量相似度; 根据最终获得的相似度按照较高相似度的顺序顺序地输入图像并发送搜索结果; 并根据特征通过关于查询结果的相关性反馈来重新计算相似性以输出转换的图像。
