In particular the median filter can reduce impulse noise. 另外,中值滤波可以有效抑制脉冲干扰。 n. 中值,中位数,中线 [C] 例句: To find the median of a data set, we first array the data in ascending or descending order. 为了计算一组数据的中位数,我们首先要把这些数据按由大到小或由小到大的...
给定的数据集中有 6 个数,先从小到大排列为 1,2,2,3,3,3,中间两个数是 2 和 3,所以中位数是(2+3)÷2=2.5。本题选项设置有迷惑性,A 选项 2 是错误的,因为直接选 2 没有考虑数据个数为偶数的情况;B 选项 3 是错误的,理由同上;D 选项 4 不在数据集中,明显错误。
2、中位數 The median of a set is another way of calculating a sort of "middle" value for a data set. In fact, the median is the actually the middle number when you put the data in order. In our example, we have two middle numbers, 72 and 72. If you get two middle numbers (b...
