基于内容的发布/订阅模糊匹配路由过滤器
发布/订阅 模糊匹配 过滤器
2009/8/31
基于模糊匹配的优化思想，设计基于内容的发布/订阅模糊匹配路由过滤器，对基于覆盖路由的模糊匹配过滤器的构造原理、模糊函数的构造和匹配规则、属性的隶属度函数和匹配阀值进行研究，并给出模糊匹配过滤器的算法描述和实验结果。研究结果表明：采用模糊匹配算法对属性进行过滤，可以快速找到符合订阅要求的发布事件消息，有效地提高系统性能。
基于尺度空间理论的Harris角点检测
Harris角点 尺度空间 LoG算子 尺度不变性
2009/8/31
研究了一种基于尺度空间理论的Harris角点检测方法。建立Harris函数的尺度空间表示,检测每个尺度水平上的极值,利用迭代算法验证每个尺度水平上LoG算子是否获得最大值,从而得到特征角点的位置及其尺度。该方法在保持Harris角点不受光照条件及摄像机姿态变化影响的同时,还能检测出多尺度下的特征点。通过实验验证该方法具有尺度不变特性,适用于尺度变化较大的视觉系统。
基于动态规划提取信号小波脊和瞬时频率
小波变换 小波脊 瞬时频率 动态规划
2009/8/31
提出一种基于动态规划提取信号小波脊和瞬时频率的方法，其基本思路是：对信号进行连续复Morlet小波变换，由变换得到的小波系数的局部模极大值初步提取其小波脊；为降低噪音影响，在初步提取的各小波脊附近选取部分小波系数，通过施加罚函数平滑噪音干扰引起的小波脊变化的不连续性，将小波脊的提取问题转变为最优化问题，采用动态规划方法计算得到新的小波脊；根据小波尺度与频率的关系由提取的小波脊识别出信号的瞬时频率。...
