在动态测试数据处理中,常常要进行稳健回归分析和最小最大值回归分析。
Robust regression analysis and minimax residual error analysis are two aspects in data processing of dynamic measurement.
模糊脉冲噪声检测器用窗口内的中值与邻近像素信息来检测脉冲噪声,而脉冲消除器用最小最大值算法计算噪声像素的估计值。
The fuzzy impulse noise detector USES the median value and neighborhood information in the window to detects impulse noise. The impulse noise canceller USES minimum-maximum estimate method.

So, sometimes people get confused when they're solving problems and call the amplitude this distance all the way from the max to the min but it's only half of that because we're only going back to the average level.
解题的时候会弄错,把这个从,最大值到最小值的距离,叫做幅值,但实际上,只有它的一半,只是它和平均值的差距。
So I differentiated this object, this is my first derivative and I set it equal to 0 Now in a second I'm going to work with that, but I want to make sure i'm going to find a maximum and not a minimum, so how do I make sure I'm finding a maximum and not a minimum?
这样我就对它求出导数了,这是一阶导数,令它等于0,一会我们就要计算了,但我先确定一下是最大值还是最小值,我怎么确定是最大值还是最小值呢
The only place q1 appears here is here, so when I differentiate again I'm going to get -2b and sure enough that's negative, which is what I wanted to know, just to check that when I'm finding this thing, I'm finding a maximum and not a minimum.
只有这一处有q1,因此二阶导数是-2b,它肯定是个负数了,这正是我们想得到的结果,这就验证了我们刚才得出的,是最大值而不是最小值
