查询词典 differencing

On the contrary, as the car runs fast, we couldn't get stable background image, and we can get only one picture as it pass by the tollbooth in order to satisfy the request of real time processing. We proposed the method of differencing image in one frame to get the moving edge.

将一帧图像的两场作为不同时刻的图像，作前后帧减影，得到运动边缘，为了克服图像中的水平边缘分割为运动边缘的问题，我们提出了一种局部门限的方案，取得了很好的运动边缘分割效果。

Axial compressor ; turbulent flow ; differencing scheme ; impeller ; curvilineal coordinate

轴流压气机；湍流流动；差分格式；叶轮；曲线坐标

Band differencing is feasible in water and irrigable field, but it couldnt monitor the changes of whole land use and its precision is the lowest. For the mufti-temporal composite method, it is difficult to choose the exact regions for change detection. Based on the previous accurate classification result, the post classification comparison method gets the best result compared with the other two methods, but also with the hand-on mistakes.

图像差值法对河流水面和水浇地的监测效果比较好，但对所有地类监测结果不令人满意，精度较低；多时相波段复合分类法中，变化土地类型训练区的确定较困难；分类后比较法是在前面土地信息准确提取的基础上进行的分析，精度较高，监测结果图也一目了然，是土地利用动态监测的一种有效方法，但它是在自动识别分类基础上进行的比较，传递了分类产生的误差。

A novel moving object detection based on adaptive background subtraction and symmetrical differencing is presented in this paper.

本文提出了一种基于背景相减法和对称差分法来进行运动目标检测的方法。

Selects the differencing algorithm to be used for impact flash detection.

选择差分算法，用于检测的影响闪光。

The half-point differencing method is used to get more accurate results.

为使计算结果更加准确，采用了半点差分格式离散。

Both of them use the technique of fractional differencing to remove the long-range dependence in the time series.

首先它们都通过分数差分的方法消除时间序列中的长相关性，然后分别用模糊自回归模型进行建模或预测。

The resolution of the first floor follows the same criteria of differencing areas.

不同区域都是以第一层的高低为比照。

This change analysis or differencing, is a very valuable tool, and we see it a lot in imagery.

这种变化分析或差异分析，就十分有用，能通过图像发现很多规律。

A simple central differencing scheme is used.

使用一个简单微分方法。

If I didn't care what anyone thought, I would.....

如果我不介意别人怎么看，我会。。。。

In recent decades, Chile has mandated earthquake-proofing for new structures, requiring that materials like rubber and features like counterweights be built into the architectural designs to allow buildings to bend and sway during temblors rather than break.

在最近数十年里，智利已经为兴建防震的新土建结构而对建筑材料提出要求，需要的材料类似于橡胶，而特性就象运用在建筑设计中的平衡物体，一旦应用以后，当地震发生时建筑就能弯曲摇摆。
