查询词典 Top Hat

A novel method that makes use of rough set theory to detect moving small target with low SNR in infrared image sequences is presented. First, Morphology Top-Hat operator is used to separate candidate small targets and extract their attributes.

提出了利用粗糙集理论处理不完整信息的能力对红外弱小目标的运动轨迹进行辨识的检测方法。

相同气速比下，喷嘴出口为"礼帽"分布时驻点的偏移量比均匀分布时大。

One uses Top-Hat morphology transform to restrain the background gradient produced

减小背景梯度是实现暂态电能质量扰动检测的关键。

It has the advantage of both the simplicity of the top-hat pdf model and reasonability of the clipped-Gaussian pdf model, and is used in the numerical simulation of Li /SF〓 gas-liquid submerged combustion.

以上述基本方程和多点δ-PDF模型为基础，在物理平面内实现了Li／SF〓气液浸没燃烧的单流体模型的数值模拟。

There's the atation-master in his frock and top-hat. There must be a big bug getting off the train here.

Then, Otus's threshold method is used to segment the image and locate the sea-sky-line, through which the target potential area can be determinated.

采用维纳自适应滤波，抑制随机噪声和高斯噪声；利用Otus阈值法分割图像，确定海天线和目标潜在区；利用Top Hat算子进行形态滤波处理，抑制平缓变化背景并保留高亮度区的目标和强噪声；选择结构元素进行形态开运算，去掉细小的背景杂波干扰；针对远距离舰艇小目标总是出现在海天线附近以及红外目标灰度高于其邻域背景的特点，确定阈值即可分离出真正的目标。
