舰船的红外图像检测技术有非常重要的作用。在军事领域,精确的舰船红外图像检测可以起到敌方舰船侦察、维护海上领土安全的作用;在民用领域,舰船的红外图像检索与特征分析,有助于海上航线管理和交通管理,从而提高海上运输的效率和安全性。本文针对舰船的红外图像检测技术,系统的介绍了红外成像的原理,基于向量机技术和图像处理技术,研究了舰船的红外图像检索和特性分析,并对某舰船海上红外图像进行了仿真试验。结果表明,基于向量机分类技术的舰船红外图像处理具有良好的效果。 相似文献

Fishing communities, the Government of Thailand Department of Fisheries, local nongovermnental organizations, universities, the Food and Agriculture Organization of the United Nations (FAO), and FAO's Bay of Bengal Program have undertaken a partnership in management of Phang-nga Bay's coastal resources. It is the first project of its kind in Thailand, and although still in the early stages, offers insights that may contribute to our knowledge of how we can improve our management of coastal resources, including the importance of (1) building relationships within the governance process; (2) combining education, enforcement, and economic incentives to achieve compliance; (3) implementing solutions early; and (4) government support of community-based decisions. These insights reinforce trends emerging in other coastal management projects in the Asian region. 相似文献

Site-based projects were initiated in Chawka Bay-Paje, Zanzibar, and Nyali-Bamburi-Shanzu, Kenya, to demonstrate the benefits of an integrated coastal management (ICM) approach for addressing coastal issues such as tourism development and enhancement of resource-dependent village economies in eastern Africa. A two-year, multidonor project used three primary strategies to make rapid, but sustainable, progress toward ICM. These included using interagency government teams for ICM planning, adopting an internationally recognized framework for ICM as a project ''road map,'' and explicitly incorporating capacity-building strategies into all aspects of the project. Within two years, integrated ICM action strategies, prepared through participatory processes, were being implemented at both sites, and both teams were working to expand the scale and scope of ICM in their nation. More importantly, the project helped create committed, capable, interagency groups that continue to work together to address urgent ICM issues. 相似文献

无人反潜系统的指挥控制问题是关系其具备实际作战能力的主要问题之一。论文在分析无人反潜系统指控原理和其自主指控水平分级的基础上,采用可变自主控制结构,研究了无人反潜系统分级可变自主指控实现的方法。该方法可赋予无人反潜系统可变的指挥控制自主性,使其在工作环境中能够实时评估自身的自主能力,并主动引入人工干预。这种具备人机智能融合特性的自主指挥控制方法更适应无人反潜系统在复杂战场环境中实战化的需求。 相似文献
