查询词典 reciprocating motion

After analyzing the characteristic of the rigid plane motion and the shortcomings of classical digital image correlation algorithms, the phase-angle position of the rigid body in the 2D image was characterized by 1D sequence signals using the method of equiangular sampling feature extraction based on circle windows. Then the generalized correlation algorithm for estimation of time delay based on wavelet transform was used to acquire the angular displacement. Finally the ultrasonic radiation force acted on the micro-component was determined by the relation between force and motion.

在研究检测对象刚体平面运动特点和分析传统数字图像相关算法局限性的基础上，采用基于圆周窗口等分角采样的特征提取方法，将二维图像中刚体的相角位置信息表征为一维采样时序信号，并通过基于小波变换的广义相关算法来估计位移前后特征序列的时延，得到刚体的旋转角位移，从而利用力与运动量的相互关系确定出作用于微构件的超声辐射力。

It has the advantage over single image in typhoon prediction. In the thesis, existing cloud motion wind algorithm is improved and a Cloud motion Wind Inferring System has been developed to derive wind fields from 2 or 3 infrared window images of FY-2C which are temporally continuous and projected by equidistance.

台风是严重影响人类生产生活的灾害性天气之一，对台风云系进行分析识别具有极其重要的现实意义，由于台风形态及结构的复杂性，单幅云图无法直观的分析其风场结构、移动趋势，通过云迹风分析，也可很好解决这样的问题。

A new diamond search algorithm for fast-matching motion estimation is proposed to replace the traditional three-step search algorithm in the motion estimation region.

并且针对块匹配运动估计给出了一种改进的钻石搜索算法代替原有的三步搜索法。

The shape information of surveillance objects is represented as macro-block coordinates. The temporal redundancy is eliminated by motion estimation within the surveillance region in the reference frame. Since the number of luminance levels is reduced due to enhancement process, the residual error of motion estimation is compressed with lossless entropy coding.

监控对象的形状信息表示为宏块坐标；监控对象之间的时间冗余通过运动估计来消除，但搜索范围限制在前一帧监控对象区域之内；由于增强处理使得监控区域的灰度级减少了，所以对运动估计的残差进行无损熵编码。

B body in motion remains in motion unless acted on by an external force.

如果没有外力的作用，运动的物体仍然保持运动状态。

Due to the effect of curvature of shell, the equation of motion of elastic waves in shell is much more complex than that in plate. The method of operator factorization can't be directly used to solve the equation of motion of elastic waves in shell by reducing it to the second order partial differential equations.
