目前，背景模型的更新算法很多，但算法中各参数的取值通常是依据经验而定。

At present, there are all kinds of updating algorithm, but the choose value of every parameter in algorithm is usually on the basis of experience.

合成孔径成像是提高图像方位向分辨率的有效方法，但算法运算量大，在机载条件下往往实时性得不到保证。

The focused synthetic aperture imaging processing is the available method to improve the azimuth resolution, but the operational quantity is so large that it could not accomplish in real time.

我本想说“记者”，但研究人员已经在开发能够收集事实并撰写新闻报道的算法。

I was hoping to say "journalist", but researchers are already developing algorithms that can gather facts and write a news story.

It's 33, 32, it's only 32 times and you can check that math at home but here lies the power of algorithmic thinking, of computational thinking as they say.

你需要33，32，对，32次,你也可以在家里自己计算，但数学算法的力量是无穷的，这就是科学家们所谓的计算机思维。

Now you might say, wait a minute. Thing's ordered, if I stop part way through and I throw away half the list, doesn't that help me? And the answer is yes, but it doesn't change the complexity.

如果我在半路上停下来,然后不去遍历剩下的数组了,这会有帮助么？答案是有帮助，但这没法改变算法的复杂度，因为我们之前怎么说来着？

And we haven't seen all of these sorts, but it's actually quite neat to recognize how different the underlying work is of each of these algorithms.

我们还没有探讨所有的排序算法，但应该很容易区分,每一种算法其内在的,不同之处。
