搜索

Image matching is very important in image processing, especially in remote sensing image processing. A nice matchimg method must possess the advantages of high matching precision, fast matching speed and the property of rotation invariant.

引 言图像匹配是通过比较样本图像和搜索图像中处于视野中的子图像之间的相关性，判断搜索图像中是否包含样本图像及其位置的过程，它是计算机视觉中的一个重要研究内容。

The paper starts by introducing the basic theory of Iterated Function System and Genetic Algorithm.

种群的进化繁殖遵从优胜劣汰，从而在可扩展的搜索空间中将搜索引向潜在的最优解。

Therefore, in this paper, importing Genetic algorithm which has been applied successfully to deal with this problem, we present a better approach to compress a binary image by using Iterated Function System and Genetic Algorithm.

然而，IFS的求解属于NP-hard问题，在复杂的约束条件下，并要在庞大的搜索空间中寻求最优解，传统的搜索方法几乎是不可能的。

Instead of multidimensional nonlinear search or iterative computation, the algorithm just uses a one-dimensional search and can reduce the computation burden.

算法的波达方向估计只需一维谱峰搜索，避免了通常多参数联合估计的多维非线性搜索及迭代运算，可明显减小算法运算量。

If not, don't worry because these are just the top searches and there are millions of other popular searches, but you may need to find out what keywords people are using and use those judiciously in your blog.

如果不是，请不要担心，因为这些都是热门搜索，并有以百万计的其他热门搜索，但你可能需要找出什麼关键词是人们利用和使用那些明智地在你的博客。

Instead, as the row is bound, I chose to get the search string, inspect it for a comma (the person is entering Lastname, Firstname), and then display the results with highlights to show them what the results matched in their search.

相反，随着行约束，我选择获取搜索字符串，检查它的一个逗号，然后显示与突出的成果来证明他们有什么结果在他们的搜索匹配。

The key points of DGA is to start evolution with initial population evenly distributed in searching space to avoid the leakiness of subspace, to accelerate the searching process by directed crossover and mutation, to improve holistic survival and adaptive ability by means of competition and parallel evolution in genetic system. However, the crossover and mutation act on different lays in space made the searching uniform.

其基本思路是以空间上均匀分布的初始点展开演化以避免子空间的遗漏，以有方向性的杂交和变异加速和调节搜索，同时杂交和变异作用在不同层面上使搜索在整体上均匀化，通过遗传系统里的并行竞争提高整个群体的生存适应力，从而达到整体优化的目的。

As an example, let us take a look at the searching results of the "Snitch Professional". The search results are displayed in an order sorted by SkinScan; namely, the likeliness generated by the skin color tone.

举一个例子，让我们看一看"Snitch Professional"的搜索结果，搜索结果是按照SkinScan的分类顺序来显示的，也就是说，是根据肤色的色浓度不同的可能性产生的结果。

But now most of the search engines present the search result to the end user with linear search result, as there are thousands search results at one time, it make the user feel difficult to find what they really want.

但目前大多数的搜索引擎以线性列表的形式为用户返回搜索结果，而搜索结果往往是成千上万的，这使得用户可能用很多时间才能找到自己需要的结果。

You need to lie low for a while.

你们得歇手一段时间

If you do, you may just be pleasantly surprised.

如果你开口问了，或许有意想不到的惊喜。
