目标识别

Based on ear recognition, an improved NMFSC(Nonnegative Matrix Factorization with Sparseness Constraints) method was proposed by imposing an additional constraint on the objective function of NMFSC, which could capture the semantic relations of coefficient matrix as orthogonal as possible. The interated rules to solve the objective function with the constraint were presented, and its convergence was proved.

针对人耳识别问题，提出了一种改进的稀疏性受限的非负矩阵因子方法，通过增加一个使系数矩阵尽可能正交的约束条件来定义原目标函数，给出求解该目标函数的迭代规则，并证明迭代规则的收敛性。

Based on the model of safe following distance, the recognition theory of the minatory objects is put forward and the model of potential menace is established, which afford a theoretic base in order to decrease the nuisance alarms and enhance the reliability of the system.

本文在安全跟车模型的基础上，提出了目标物有效性识别理论，并建立了潜在威胁目标的判别模型，为减少系统的虚警率、提高系统的可靠性提供了理论支持。

精确的目标检测是目标跟踪和识别的重要前提。

In chapter 4, the dynamic one-dimensional range profiles of the targets in flight are applied to recognition experiment.

第四章应用目标运动过程中的动态一维距离像完成了几类弹头目标的分类识别。

Meanwhile, we proposed the signal data overflow handling algorithm to deal with the possible missile target missing caused by the infrared interference, and the infrared signal flicker because of the infrared attenuation in atmosphere.

简要介绍了反坦克导弹红外测角仪的信息处理系统组成原理，讨论了红外测角仪抗红外干扰的信息处理方法，导弹目标信号的确定要通过真假红外信号的模式识别和航迹判别处理等才能最终确定，同时对由于大气红外衰减造成的红外信号闪烁以及其它干扰造成的导弹目标丢失情况，设计了信号数据溢出处理模块。

First,the target area is confirmed by using target matching method and the number of pels of this area is estimated.

对于相邻的两帧目标图像，如果成像效果没有大的变化，则识别出的目标边界也应该基本一致。

Aimed at low-SNR infrared images, this paper analyzed principle and computational method of Zernike moments, proved rotation invariant property, proposed a method for low-SNR infrared target detection based on Zernike moments,and compared target recognition effect among template matching, Hu moments and Zernike moments via experiment.

由于低信噪比红外图像本身所具有的目标特征很不明显、背景特征比较强等特点，模板匹配识别方法、Hu不变矩等并不适用于低信噪比红外目标检测。

All these results suggest that the ability to temporally maintain fine structure details contributes to perceptual integration of correlated leading and lagging sounds, which in turn, contributes to releasing speech from informational masking in noisy, reverberant environments.

因此，在嘈杂混响环境下，听觉系统需要对声波的精细结构进行存储以便对直达声和反射声进行有效的知觉整合，带来各种线索帮助听者在知觉层次上对目标声音和干扰声音进行分离，从而提高对目标声音的探测和识别，达到去掩蔽的作用。

The software includes two modules. One is to evaluate and manage how smoke bomb can shield the thermal images, which can be used as the guide in the development and improvement of thermal smoke bomb. The other is to process the data of thermal images under smoke-screen to locate target in the shortest time and improve the quality of the target thermal images, which can be used as the reference to further design for development and improvement of thermal image.

该软件主要包括两大功能模组：1红外烟幕对热像图遮蔽效果的评价和管理模块，利用该模块研究红外烟幕环境对红外与热像传输影响的定量测试与评价，指导红外烟幕弹的研制与改进；2红外烟幕遮蔽条件下热像图增强处理模块，该模块主要是研究采用一定的处理方法，改善烟幕遮蔽条件目标热像图的观察效果，争取最短时间发现或识别目标，为今后热像仪的研制设计、改进提供参考依据。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
