查询词典 robust statistics

In order to mine the structure difference of the chinese and english characters,the gradient information of the pixel based horizontal and vertical stroke vector,gradient orientation correlogram and the relative gray information of the location correlation pixels based census transform histogram are used,they can be robust to illumination,noise and resolution and so on,and can be applied to camera-based images.

为了能够很好地挖掘中英文字符之间的结构差异，提出采用基于象素梯度信息的水平垂直笔画向量和梯度方向相关图，以及基于位置相关象素的相对灰度信息的Census变换直方图，它们对光照、噪声以及分辨率等都具有良好的鲁棒性，可以应用于基于相机的图像。

With the object correspondence, the occlusion problem can be solved easily and the 3-D probability distribution of moving objects can also be estimated more precisely. These advantages make the results of objects tracking and correspondence more robust and reliable.

有了物体的对应关系，就可以解决物体交错所造成的追踪错误，并且能够更加正确的估测三维物体的机率分布，使多物体的追踪和对应更加准确而可靠。

Finally, the most striking creation of this paper is to propose a new solution to OOI correspondence problem between wide baseline images, named multi-epipolar-line constraint. It defeats existing methods by generating the more accurate one-to-one OOI correspondence and thus can be more suitable for real-time system. The experimental results show that our new method is very portable, robust and efficient.

它弥补了以往基础矩阵法与单应矩阵法的缺陷，能够更适用于实时视觉系统，经过实验证明，它能够生成十分准确的一对一对应的感兴趣目标，并且不需要借助任何附加的对图像内容进行搜索的过程，鲁棒高效。

Firstly, modal responses were estimated by the application of robust second-order blind identification technique on the measured vibration signals. And then, modal shapes were extracted from the de-mixing matrix above. Finally, frequency and damping ratios could be obtained from the modal responses using each single degree of freedom mode.

运用该法提取系统／结构模态参数的步骤为：首先利用稳健SOBI的盲源分离方法采集的信号进行分离，然后将分离矩阵作为结构／系统的模态振型矩阵，最后再对各个分离后的单自由度信号提取频率、阻尼比参数。

Finally, simulation experiments of two algorithms are carried out, results demonstrate that the watermark is invisible and robust against some attacks, such as crop, common noise and JPEG compress. It also has certain counteractant ability against a comprehensive attack.

仿真结果表明，实现的水印具有不可见性，而且对于常见的噪声、剪切、JPEG压缩具有较强鲁棒性，对于综合性攻击也具有一定的抵抗能力。

His robust strength was a counterpoise to the disease.

针对噪声方差不确定的约束系统，讨论了一种鲁棒滚动时域估计方法。

A simple cubic equation is deduced to describe the length of hidden messages with relatively high robust and precision.

该文还给出了具体的检测步骤和相关的理论推导。

The color sorting of rice is an important working procedure during quality control and is just to blow out yellow rice, discolored rice and other impurities like cullet and sand to improve the quality and safety factor of rice.Currently, there is a relatively mature market for such machine, and the market demand for the machine is quite robust.

大米色选是大米加工企业最终质量控制和质量强化的一道重要工序，由此去除黄粒米等变色米和碎玻璃及沙子等杂质，从而达到提高大米质量和食用安全系数。
