However, the topology of the unknown surface may be very complex some time. It isreally a hard work to generate the complex surface just by these scatter points.
因此,由采样得到的散乱点生成所对应的未知曲面,并保证生成曲面的拓扑结构与原曲面一致,就是一个相当有难度的问题。

Experimental Results using real SAR images demonstrate that the method can not only reduce the speckle but also preserve edges and radiometric scatter points.
用真实SAR图像实验表明,该文提出的方法能够有效地抑制斑点噪声,同时能够很好地保存边缘细节结构与强散射中心。
The concept of regression goes back to the mathematician Gauss, who talked about fitting a line through a scatter of points.
回归这个概念要追溯到数学家高斯,讨论的是从若干散点中切合出一条直线。
And you will see data points which scatter around a straight line.
你可以看到这些点,分布在一条直线周围。

What Gauss did was said, let's fit a line through the point-- the scatter of points--and that's called the regression line.
高斯说,做这样的一条直线,切合所有散点,这就是回归直线
This could be 1979, this could be 1980, and we keep adding points so we have a whole scatter of points.
假设这里是1979年,这里是1980年,一直添加数据点,就形成了一个散点图
