查询词典 concave line

By using the transfer matrix of the beam propagation,the movement of the low-order nonlinear ghost image s was calculated when high-power Gaussian laser beam passes through the single convexo-convex lens,the single concavo-concave lens and the 4F system and then the movable rules were analyzed.

It modified some terms of the initial formula, which made the snake model not only precisely extract the edge of the protruding object in images but also approach to the concave part of the edge. It introduced exterior sanction energy, which could adaptively change its value to enlarge suction, so that control points could quickly constringe to the real contour without relying on the initial contour. Combined with pattern matching, this new method could increase the precision of transferring the result of edge extraction from one slice to another.

通过调整原始公式的一些参数使得该模型不但能精确地提取图像中的凸形物体的边缘，而且能够接近边缘的凹陷处；引入自适应改变大小的外部约束能量来增大外能的吸引范围，使控制点能够不依赖于初始轮廓而快速地收敛到目标的真实轮廓；结合匹配技术，提高边缘提取结果层间传递的精度。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
